  • Patent number: 10359664
    Abstract: A display device includes a display surface with pixels including four sub-pixels of four colors, and being arrayed in a matrix of a first viewing angle direction and a second viewing angle direction orthogonal thereto. The first viewing angle direction in a direction parallel to the display surface of a main viewing angle direction that intersects with the display surface. A reflective member, first substrate, a second substrate facing the first substrate, a color filter with filters of four colors corresponding to the four sub-pixels, and a scattering member is provided on the second substrate. For the color filter, a change in transmittance of the filters per pixel in the main viewing angle direction is smaller than a change in transmittance of the filters per pixel in a direction orthogonal to the first viewing angle direction in the second viewing angle direction parallel to the display surface.
