Abstract
A light emitting display device includes a first color conversion pattern with a first color conversion material located correspondingly to an emitting area of a first sub-pixel, and optionally a second color conversion pattern with a second color conversion material located correspondingly to an emitting area of a second sub-pixel, and a while light emitted from an electro-luminescence element can be converted to a red light and a green color light in the first and second sub-pixels, respectively, and thus, the device can implement red light and green light with improved color purity and light efficiency. It is possible to maximize out-coupling efficiency of light emitted from the electro-luminescence element and to improve a color purity and light efficiency of the device.
