Display device and electronic device having anti-reflection member provided between black matrix and substrate
View Patent ↗There is provided a display device including a plurality of light emitting elements over a first substrate, and an anti-reflection member configured to prevent reflection of light from a first substrate side at a boundary portion in a pixel region corresponding to each of the light emitting elements, the anti-reflection member being on a second substrate side where a second substrate faces the first substrate.
1. A display device comprising:
a plurality of light emitting elements provided on a first substrate;
a second substrate facing the first substrate;
an anti-reflection member positioned at the second substrate at a boundary portion in a pixel region corresponding to the plurality of light emitting elements;

a color filter layer provided in the pixel region at the second substrate,
wherein the anti-reflection member is configured to prevent reflection of light from at least one of the plurality of light emitting elements, and the anti-reflection member is provided at a surface of the black matrix in a same area as the black matrix, and
wherein the anti-reflection member is provided in the color filter layer.
2. The display device according to claim 1 , wherein the anti-reflection member is positioned at an edge portion between a first color filter and a second color filter, and wherein an anti-reflection target wavelength of the anti-reflection member is associated with a color wavelength of at least one of the first color filter and the second color filter.
3. The display device according to claim 2 , wherein the anti-reflection target wavelength is based on a color wavelength of the first color filter if the color wavelength of the first color filter is longer than the second color filter.
4. The display device according to claim 1 , wherein the anti-reflection member includes an anti-reflection coating.
5. The display device according to claim 1 , wherein a moth eye structure is formed on a surface of the anti-reflection member.
