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.

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 method of manufacturing a display device, which is provided using an inkjet apparatus that provides a liquid composition including a scatterer, includes performing j scanning stages to provide a first composition to i unit display areas among n unit display areas (j is a natural number equal to or greater than 2), and performing a first compensation-scanning stage to provide the first composition to first to (i−1)-th unit display areas among the n unit display areas. The i unit areas of the first head unit provide the first composition to the first unit display area to an i-th unit display area among the n unit display areas in a first scanning stage among the j scanning stages. The first head unit is shifted in the second direction by one unit display area in every scanning stage of the j scanning stages.
