Description

Display Device The embodiments of the present disclosure relate to a display device. As the information society develops, the demand for display devices to display images is increasing in various forms, and recently, various display devices such as liquid crystal displays and organic light-emitting diodes (OLEDs) are being utilized. The display device may include an encapsulation layer and a color filter layer. The encapsulation layer may be a layer that protects a light-emitting element. The color filter layer may change the light emitted from the light-emitting element into a predetermined color. FIG. 1 is a system configuration diagram of a display device according to embodiments of the present disclosure. FIG. 2 is a drawing showing a subpixel according to embodiments of the present disclosure. FIG. 3 is a plan view of a plurality of subpixels according to embodiments of the present disclosure.
