Abstract: A display device is provided. A display device includes a plurality of pixels arranged in a row axis and in a column axis that intersects the row axis, a first substrate on which a light-emitting element disposed in each of the pixels is disposed, a second substrate which faces the first substrate, and a first wavelength conversion pattern disposed on the second substrate in a first pixel column and which converts wavelength of light emitted from the light-emitting element. The first wavelength conversion pattern includes a first main pattern part arranged in a stripe fashion along the column axis and a protruding pattern part projected from the first main pattern part toward at least one of first and second directions of the row axis.

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: A display device includes a base portion including a pixel area including a light-transmitting area and a light-blocking area; a projection portion disposed on the light-blocking area of the base portion and including a first sub-color filter and a second sub-color filter overlapping over an overlap area; a light-blocking member disposed on the projection portion and overlapping the base portion; and a spacing member disposed on the light-blocking member, made of the same material as the light-blocking member and overlapping the projection portion. The first sub-color filter includes a first color pigment, the second sub-color filter includes a second color pigment different from the first color pigment, a first width of the first sub-color filter in a first direction is different from a second width of the second sub-color filter in the first direction, a third width of the first sub-color filter in a second direction is different from a fourth width of the second sub-color filter in the second direction, and the second direction is a direction intersecting the first direction.
