Abstract
In one aspect, a display device comprising: a lower substrate, a light-emitting element formed on the lower substrate and comprising a plurality of pixels, an upper substrate disposed on the light-emitting element with a gap therebetween sealed with a sealant, a filler filling the gap between the light-emitting element and the upper substrate, and a light-absorbing material formed between the lower substrate and the upper substrate and selectively absorbing light of a certain wavelength range is provided.
Claims20
A display device comprising:
- a lower substrate;
- a light-emitting element formed on the lower substrate and comprising a plurality of pixels;
- an upper substrate disposed on the light-emitting element with a gap therebetween sealed with a sealant;
- a filler filling the gap between the light-emitting element and the upper substrate;
- and
- a light-absorbing material formed between the lower substrate and the upper substrate and selectively absorbing light of a certain wavelength range.
A display device comprising:
- a lower substrate;
- a light-emitting element formed on the lower substrate and comprising a plurality of pixels, each comprising a plurality of subpixels;
- an upper substrate disposed on the light-emitting element with a gap therebetween sealed with a sealant;
- a filler filling the gap between the light-emitting element and the upper substrate;
- and
- a light-absorbing layer formed between the lower substrate and the upper substrate and selectively absorbing light of a certain wavelength range,
- wherein each of the pixels comprises subpixels which respectively emit red light, green light, and blue light, and the light-absorbing layer is formed at a position corresponding to each of the subpixels and is made of a material which absorbs light of a different wavelength region for each of the subpixels.
A method of manufacturing a display device, the method comprising:
- forming a light-emitting element on a lower substrate;
- providing a filler and mixing the filler with a light-absorbing material which selectively absorbs light of a certain wavelength range;
- providing the filler on the light-emitting element;
- coating a portion of the lower substrate with a sealant;
- and
- attaching an upper substrate to the sealant so as to seal a space between the lower substrate and the upper substrate.
A method of manufacturing a display device, the method comprising:
- forming a light-emitting element, which comprises a plurality of pixels, on a lower substrate;
- providing a filler on the light-emitting element;
- coating a portion of the lower substrate with a sealant;
- forming a light-absorbing layer, which selectively absorbs light of a certain wavelength range, on a surface of an upper substrate;
- and
- attaching the upper substrate to the sealant so as to seal a space between the lower substrate and the upper substrate,
- wherein the forming of the light-absorbing layer comprises:
- dispersing and dissolving a light-absorbing material in a solvent;
- and
- coating the light-absorbing material on a surface of the upper substrate.
