Abstract: 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.

Abstract: An organic light emitting diode (OLED) display device is described that includes a shared cathode between OLED pixels as well as auxiliary lines that are formed between rows and/or columns of the OLED pixels. As the cathode is shared between many if not all of the pixels of display device, resistance within the cathode can affect the brightness of those pixels that are further from the cathode's voltage source. The auxiliary lines serve to counteract the voltage drop caused by this resistance. The auxiliary lines are electrically connected to the cathode in close proximity to individual pixels of the display.

Abstract: An organic light emitting display element includes a substrate, a lower electrode positioned on the substrate, at least one organic light emitting layer positioned on the lower electrode, a metal doped layer positioned on the organic light emitting layer, and an upper electrode positioned on the metal doped layer that includes a conductive material, and is configured to transmit light. Such organic light emitting display element is capable of minimizing degeneration and damage to the organic light emitting layer caused by sputtering.
