  • Patent number: 11971633
    Abstract: An electrode structure includes: a plurality of pixel electrodes arranged separately from each other; and a plurality of dielectric layers laminated in a first direction with respect to the plurality of pixel electrodes, in which the plurality of dielectric layers includes: a first dielectric layer that spreads over the plurality of pixel electrodes in a direction intersecting with the first direction; and a second dielectric layer that includes dielectric material having a refractive index higher than that of the first dielectric layer, sandwiches the first dielectric layer together with the plurality of pixel electrodes, and has a slit at a position overlapping space between pixel electrodes adjacent when viewed from the first direction.

  • Patent number: 10908444
    Abstract: [Object] To provide a display device, a method for producing a display device, and a display apparatus of projection type, which are capable of suppressing deterioration of image quality attributable to a depressed space between pixel electrodes. [Solving Means] A display device of the present disclosure includes pixel electrodes formed for individual pixels and an insulating film for insulation between the pixel electrodes. The insulating film is so formed as to protrude from an electrode surface between the pixel electrodes. A display apparatus of projection type of the present disclosure uses the display device of the present disclosure as a light modulator to module light from a light source. A method for producing a display device of the present disclosure having pixel electrodes formed for individual pixels and an insulating film for insulation between the pixel electrodes includes forming the insulating film as to protrude between the pixel electrodes.
