A light emitting display panel can include a first pixel and a second pixel disposed adjacent to each other on a planarization layer; an anode disposed in each of the first and second pixels; a light emitting layer disposed in each the first and second pixels; a main cathode disposed in each of the first and second pixels; a boundary groove in the planarization layer in an area between the first and second pixels; a boundary region cathode disposed in the boundary groove, in which the boundary region cathode and the main cathode are spaced apart from each other in the boundary groove, and the boundary region cathode and the main cathode are electrically connected to each other in a region outside of the boundary groove.

Light emitting display panel and light emitting display apparatus including the same

The present disclosure provides an organic light emitting diode display device including: first to third color filter layers disposed corresponding to red, green, and blue sub-pixels, respectively; and a fourth color filter layer alternately arranged including a color layer having the same color as any one of the first to third color filter layers in a white sub-pixel in each of a plurality of pixels, and having a smaller height than the first to third color filter layers. Additional color filter layers may also be included. The display device of the present disclosure has lower reflectance and enhanced black color expression.

Organic light emitting diode display device

A thin film transistor array substrate and an organic light emitting diode (OLED) display device including the same are disclosed in which a color layer is disposed on a first substrate corresponding to a white sub-pixel and a non color filter area is included in a second substrate corresponding to the white sub-pixel, and thus, it is possible to lower an amount of reflectance of external light, increase a luminance efficiency, and reduce a power consumption of the OLED display device.
