WHITE ORGANIC LIGHT EMITTING DIODE DISPLAY DEVICE USING MICRO CAVITY

摘要

The white organic light emitting diode (W-OLED) display device using the micro-cavity structure of the present invention emits light using W-OLED and implements color using a color filter. In an OLED display device, a sub-pixel is divided into two regions for at least one color pixel, and a micro-cavity structure is applied to only one divided sub-pixel to prevent color shift according to a viewing angle and to achieve high luminance. A substrate for arranging a plurality of pixels composed of red, green, and blue subpixels; Red, green and blue color filters formed on each of the red, green and blue sub-pixels; An overcoat layer formed on a substrate on which the red, green and blue color filters are formed; A pixel electrode formed on each of the red, green and blue sub-pixels on the overcoat layer; An organic compound layer formed on the pixel electrode; And a common electrode formed on the organic compound layer, the first subpixel region divided by dividing the subpixel into first and second subpixel regions for at least one subpixel among the red, green, and blue subpixels. It is characterized by applying a micro-cavity structure only.
