Description

Display Device Including Circuit Part and Emission Part This specification relates to a display device comprising a circuit portion and a light-emitting portion. Recently, panel displays such as liquid crystal display devices (LCDs), organic light emitting diode display devices (OLEDs), and field emission display devices (FEDs), which have excellent characteristics such as thinness, lightness, and low power consumption, have been developed and are being applied in various fields. Such a display device comprises a display panel that displays an image and a driving unit that supplies signals and power to the display panel, and the driving unit comprises a gate driving unit and a data driving unit that respectively supply gate voltage and data voltage to each pixel area of the display panel. FIG. 1 is a drawing illustrating a display device according to an embodiment of the present specification. FIG. 2 is a drawing illustrating the first to third subpixels of a display device according to an embodiment of the present specification. FIG. 3 is a drawing illustrating the first to third light-emitting parts of a pixel of a display device according to an embodiment of the present specification. FIG. 4 is a drawing illustrating a horizontal pixel line of a display device according to an embodiment of the present specification. FIG. 5 is a cross-sectional view illustrating a circuit part and a light-emitting part of a display device according to an embodiment of the present specification. The terms used in the embodiments of this specification have been selected to be as widely used and general as possible, taking into account their functions; however, these may vary depending on the intent of those skilled in the art, case law, the emergence of new technologies, etc. In specific cases, terms have been arbitrarily selected by the applicant, and in such cases, their meanings will be described in detail in the relevant explanatory sections. Therefore, terms used in this specification should be defined not merely by their names, but based on their meanings and the content throughout this disclosure. When a part of a specification is described as "including" a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components. The expression "at least one of a, b, and c" as used throughout the specification may encompass 'a alone', 'b alone', 'c alone', 'a and b', 'a and c', 'b and c', or 'a, b, and c all'. The advantages and features of the present invention, and the methods for achieving them, will become clear from the embodiments described below in detail together with the accompanying drawings. Shapes, areas, ratios, angles, numbers, etc. disclosed in the drawings for describing embodiments in this specification are exemplary, and therefore the embodiments of this specification are not limited to those depicted. In describing embodiments, if it is determined that a detailed description of related prior art could unnecessarily obscure the essence of the embodiment, such detailed description is omitted. In cases where terms such as 'includes,' 'have,' or 'consists of' are used in this specification, other parts may be added. When a component is expressed in the singular, it includes cases where it includes the plural unless specifically stated otherwise. Furthermore, in interpreting the component, it is interpreted to include an error range even without separate explicit description. In the case of a description of a positional relationship, for example, when the positional relationship between two parts is described using expressions such as "on," "on the upper side," "on the lower side," or "next to," one or more other parts may be located between the two parts. When an element or layer is referred to as being "on" another element or layer, it includes cases where another layer or element is placed directly on top of another element or in between. Additionally, terms such as "first," "second," etc., are used to describe various components, but these components are not limited by these terms. These terms are used merely to distinguish one component from another. Accordingly, the first component mentioned below may be the second component within the technical scope of the present invention. The area, length, or thickness of each component described in the specification is illustrated for convenience of explanation and the present invention is not necessarily limited to the area and thickness of the illustrated components. The features of each of the various embodiments of this specification may be combined or combined with one another, either partially or wholly, and may technically enable various interlocking and operation. Each embodiment may be implemented independently of one another or together in an associated relationship. Furthermore, the terms described below are defined considering their functions in the implementation of this
