Abstract

A liquid crystal apparatus includes a liquid crystal layer sandwiched between a counter substrate and an element substrate in which a plurality of pixels are disposed, and light is incident on the liquid crystal layer from the counter substrate. The counter substrate includes a first microlens disposed for each pixel. The element substrate includes a switching element disposed for each pixel and a second microlens disposed for each pixel. The second microlens includes a flat portion at the center of the lens.

Claims

1. A liquid crystal apparatus, comprising:

a first substrate;

a second substrate disposed to face the first substrate via a liquid crystal layer; and

a display region in which a pixel is disposed,

light being incident on the liquid crystal layer from the first substrate, wherein

the first substrate includes a first microlens disposed to correspond to the pixel,

the second substrate includes a switching element and a second microlens that are disposed to correspond to the pixel, and

the second microlens includes a flat portion at a center.

2. The liquid crystal apparatus according to claim 1, wherein

a maximum length of the flat portion in plan view is greater than or equal to 1 μ

m.

3. The liquid crystal apparatus according to claim 2, wherein

a maximum length of the flat portion in plan view is less than or equal to 70% of a length of a diagonal line of the pixel.

4. The liquid crystal apparatus according to claim 1, wherein

the first substrate includes a third microlens disposed to correspond to the first microlens.

5. An electronic apparatus comprising the liquid crystal apparatus according to claim 1.
