Description

Display Device The embodiments of this specification relate to display devices. With technological advancements, display devices can provide not only image display functions but also shooting functions and various sensing functions. To this end, the display device must be equipped with optical electronic devices (also referred to as light receiving devices or sensors), such as cameras and sensing sensors. Since optoelectronic devices must receive light from the front of the display device, they must be installed in a location advantageous for light reception. Consequently, conventionally, cameras (camera lenses) and detection sensors had to be installed so that they were exposed on the front of the display device. As a result, optoelectronic devices are being placed in areas where the display panel bezel is widened or where notches or physical holes are formed in the display area. In other words, as optical electronic devices such as cameras and detection sensors that receive light from the front and perform specific functions are provided in the display device, the bezel on the front of the display device may become larger or restrictions may arise on the front design of the display device. Furthermore, when the display device is equipped with optical electronic devices, unexpected degradation of image quality may occur due to the structure in which the optical electronic devices are provided. FIGS. 1a to 1e are drawings for illustrating a display device according to embodiments of the present specification. FIG. 2 is a drawing for explaining the system configuration of a display device according to embodiments of the present specification. FIG. 3 is a drawing for illustrating an example of a subpixel according to embodiments of the present specification. FIG. 4 is a diagram illustrating the arrangement of subpixels in a general area and an optical area according to embodiments of the present specification. FIGS. 5A and FIGS. 5B are drawings for illustrating the arrangement of signal lines in a display panel according to embodiments of the present specification. FIGS. 6 and FIGS. 7 are drawings for illustrating optical regions according to embodiments of the present specification. FIGS. 8 to 13 are drawings for illustrating embodiments according to various combinations of the first connecting wire and the second connecting wire in a display device according to embodiments of the present specification. FIGS. 14 to 18 are drawings for illustrating embodiments of a display device according to the embodiments of the present specification. Hereinafter, some embodiments of the present specification will be described in detail with reference to the exemplary drawings. In assigning reference numerals to the components of each drawing, the same components may have the same reference numeral as much as possible, even if they are shown in different drawings. Furthermore, in describing the present specification, if it is determined that a detailed description of related known components or functions may obscure the essence of the present specification, such detailed description may be omitted. Where terms such as "comprising," "having," or "consisting of" are used in the present specification, other parts may be added unless "only" is used. Where a component is expressed in the singular, it may include a plural unless there is a special explicit description otherwise. Additionally, terms such as first, second, A, B, (a), (b), etc., may be used to describe the components of this specification. These terms are used merely to distinguish the components from other components, and the nature, order, sequence, or number of the components are not limited by such terms. In describing the positional relationship of components, where it is stated that two or more components are "connected," "combined," or "joined," it should be understood that while the two or more components may be directly "connected," "combined," or "joined," they may also be "connected," "combined," or "joined" with other components "intervened." Here, the other components may be included in one or more of the two or more components that are "connected," "combined," or "joined" with one another. In describing the temporal flow relationship regarding components, methods of operation, or methods of production, for example, when the temporal or sequential relationship is described using "after," "following," "next," or "before," it may include cases where the relationship is not continuous unless "immediately" or "directly" is used. Meanwhile, where numerical values or corresponding information regarding a component (e.g., levels, etc.) are mentioned, even without separate explicit notation, the numerical values or corresponding information may be interpreted as including a range of error that may occur due to various factors (e.g., process factors, internal or external shocks, noise, etc.). Hereinafter, various embodiments of the present specification will be
