Abstract
An optical substrate includes a first substrate, a light-transmitting layer disposed at the first substrate, concave portions provided in the light-transmitting layer, and a lens layer disposed so as to fill the concave portions. The light-transmitting layer is constituted by a plurality of light-transmitting layers, and an edge of the concave portion is in contact with an edge of an adjacent concave portion adjacent to the concave portion.
Claims10
An optical substrate comprising:
- a substrate;
- a light-transmitting layer disposed at the substrate;
- a concave portion provided at the light-transmitting layer;
- and
- a lens layer disposed filling the concave portion, wherein
- the light-transmitting layer is constituted by a plurality of layered films including a first layered film, a second layered film and a third layered film,
- the concave portion is formed by the plurality of layered films,
- the concave portion is provided across the second layered film and the third layered film without being provided across the first layered film,
- the first layered film is formed outside a forming region of the concave portion, and
- an edge of the concave portion is in contact with an edge of an adjacent concave portion adjacent to the concave portion.
