Abstract
A display device including color filters overlapping each other on a non-emitting area of an upper substrate which is opposite to a lower substrate is provided. In the display device, color filters disposed close to a white emitting area include a same material, and the color filters extend a greater distance onto a non-emitting area disposed near the white emitting area, relative to distances extended onto other non-emitting areas. Thus, the display device may prevent light-leakage from the white emitting area.
Claims20
A display device comprising:
- a lower substrate including a display area;
- an upper substrate including a white emitting area, a first non-emitting area, a first emitting area, a second non-emitting area and a second emitting area, which are disposed side by side on the display area of the lower substrate;
- a first color filter on the first emitting area of the upper substrate, the first color filter extending by a first distance onto the first non-emitting area and extending by a second distance onto the second non-emitting area;
- and
- a second color filter on the second emitting area of the upper substrate, the second color filter overlapping with the first color filter on the second non-emitting area,
- wherein the first distance of the first color filter extending onto the first non-emitting area of the upper substrate is greater than the second distance of the first color filter extending onto the second non-emitting area of the upper substrate.
3 more elements
A display device comprising:
- a first row including a first white emitting area, a first emitting area, and a second emitting area emitting different colors of light from each other, the white emitting area, the first emitting area, and the second emitting area repeatedly arranged;
- and
- a second row including a second white emitting area, a third emitting area, and a fourth emitting area arranged in a staggered order relative to the emitting areas of the first row,
- wherein the first white emitting area and the second white emitting area are each surrounded by at least two other emitting areas.
1 more element
A display device comprising:
- a lower substrate;
- a light emitting structure on the lower substrate, the light emitting structure emitting white light;
- an upper substrate including:
- a first non-emitting area between a first emitting area and a second emitting area, and
- a second non-emitting area between a white emitting area and the second emitting area;
- a first color filter overlapping the first emitting area and at least part of the first non-emitting area;
- and
- a second color filter overlapping the second emitting area, the second color filter extending by:
- (i) a first distance into a first portion of the first color filter in the first non-emitting area to block the white light from emitting from the first portion;
- and
- (ii) a second distance into a second portion of the second non-emitting area to prevent leaking of the white light through the second portion, wherein the second distance is greater than the first distance.
