Abstract: A color conversion substrate includes a base on which first to third light outputting regions and a light shielding region surrounding the first to third light outputting regions are defined; first to third color filters on the base in the first to third light outputting regions, respectively; a first light shielding member on the first color filter in the light shielding region; a light transmission pattern on the first color filter; a first wavelength conversion pattern on the second color filter and which converts light of a first color into light of a second color; and a second wavelength conversion pattern on the third color filter and which converts the light of the first color into light of a third color. A first opening located in the light shielding region is defined in at least one of the light transmission pattern and the first and second wavelength conversion patterns.

Abstract: An organic light emitting display device comprising: a substrate; a first pixel electrode disposed on the substrate; a pixel defining film disposed on the first pixel electrode and having a first opening at least partially exposing the first pixel electrode; a first organic light emitting layer disposed on the pixel defining film and overlapping with the first opening of the pixel defining film; and a black matrix disposed on the first organic light emitting layer and having a first opening overlapping with the first organic light emitting layer. Light having passed through the first opening of the black matrix is one of red light, green light, and blue light. The first opening of the black matrix may have a shape with a curved portion.

Abstract: An organic light emitting diode display includes: a display panel; and a color conversion panel positioned on the display panel. The color conversion panel includes: a substrate; a color filter layer disposed under the substrate; a first light blocking layer disposed under the color filter layer; and a first color conversion layer, a second color conversion layer, and a third color conversion layer positioned under the first light blocking layer. The color filter layer includes a first color filter, a second color filter, and a third color filter, the first light blocking layer includes a first portion that overlaps the first color filter, a second portion that overlaps the second color filter, and a third portion that overlaps the third color filter, and the first portion, the second portion, and the third portion are connected.
