Abstract
There is provided a display device including: a first substrate that is a silicon substrate and on which a plurality of light-emitting elements is formed; a second substrate including, on a surface, a color filter layer including a plurality of color filters arrayed and a microlens layer including a plurality of microlenses arrayed that are layered in this order, the microlens layer being arranged to face the plurality of light-emitting elements with respect to the first substrate; and an adhesive layer that fills a gap between the first substrate and the second substrate for bonding the first substrate and the second substrate together.
Claims16
A display device comprising:
- a first substrate on which a plurality of light-emitting elements is formed;
- a second substrate including, on a surface, a color filter layer including a plurality of color filters arrayed, a planarizing layer formed on the color filter layer, and a microlens layer formed on the planarizing layer, the microlens layer including a plurality of microlenses arrayed, the microlens layer being arranged to face the plurality of light-emitting elements with respect to the first substrate;
- and
- an adhesive layer that fills a gap between the first substrate and the second substrate for bonding the first substrate and the second substrate together, wherein
- each of the microlenses has a convex shape protruding toward a corresponding one of the light-emitting elements, and
- a refractive index of a material of the adhesive layer is smaller than a refractive index of a material of the microlens layer.
An electronic device comprising
- a display device that performs display on a basis of an image signal, wherein
- the display device includes
- a first substrate on which a plurality of light-emitting elements is formed,
- a second substrate including, on a surface, a color filter layer including a plurality of color filters arrayed, a planarizing layer formed on the color filter layer, and a microlens layer formed on the planarizing layer, the microlens layer including a plurality of microlenses arrayed, the microlens layer being arranged to face the plurality of light-emitting elements with respect to the first substrate, and
- an adhesive layer that fills a gap between the first substrate and the second substrate for bonding the first substrate and the second substrate together, wherein
- each of the microlenses has a convex shape protruding toward a corresponding one of the light-emitting elements, and
- a refractive index of a material of the adhesive layer is smaller than a refractive index of a material of the microlens layer.
