摘要： Disclosed are display panels and methods of manufacturing substrates. The display panel comprises a lower display substrate that includes a plurality of light emitting elements, and an upper display substrate that includes a color control layer and is on the lower display substrate. The color control layer includes a plurality of walls each of which includes a wall base including an organic material and a reflective layer including a metallic material, and the color control layer also includes a plurality of color control parts which are disposed between the plurality of walls and at least one of which includes a quantum dot. The reflective layer surrounds at least a portion of a sidewall of the wall base, which results in an increase in luminous efficiency and an improvement in brightness.

摘要： A display apparatus includes: a display element layer having first to third light-emitting regions and a non-light-emitting region, and including light-emitting elements along one direction and corresponding to the first to third light-emitting regions to provide source light; a light control unit on the display element layer, and including a base resin and scatters, and having openings overlapping with the first and second light-emitting regions; light conversion units in the openings, and including quantum dots; and first to third color filters on the light control unit and the light conversion units, and overlapping with the first to third light-emitting regions. The light control unit includes a first portion overlapping with the non-light-emitting region, and a second portion overlapping with the third light-emitting region, that form a step difference with each other; and a width of the first portion is greater than a thickness of the second portion.

摘要： A display device includes a first substrate, pixel structures, and first, second, and third optical filters. The first substrate has a plurality of pixel regions each including first, second, and third sub-pixel regions. The pixel structures are disposed on the first substrate. The first, second, and third optical filters are disposed to overlap the first, second, and third sub-pixel regions, respectively, on the pixel structures. Each of the first, second, and third optical filters has a tetragon shape. A long axis of the tetragon is parallel to row or column directions of the pixel regions. The third optical filter overlaps a first virtual line located between a side of the first optical filter and a side of the second optical filter which is adjacent to the side of the first optical filter. The first virtual line extends parallel to the sides of the first and second optical filters.
