Abstract

Provided is a liquid crystal device including a first substrate and a second substrate which face each other with a liquid crystal layer interposed therebetween, wherein a plurality of columnar spacers for maintaining a gap between the first substrate and the second substrate is arranged on a surface of a liquid crystal layer side of the first surface, and spacer reception portions are arranged on a surface of a liquid crystal layer side of the second substrate in regions which face the columnar spacers, and wherein the spacer reception portions include contact reception portions which are in contact with the columnar spacers and non-contact reception portions which are not in contact with the columnar spacers.

Claims (10)

1. A liquid crystal device, comprising:

a first substrate and a second substrate which face each other with a liquid crystal layer interposed therebetween;

a plurality of columnar spacers arranged on a surface of a liquid crystal layer side of the first surface, said columnar spacers maintaining a gap between the first substrate and the second substrate; and

a plurality of spacer reception portions arranged on a surface of a liquid crystal layer side of the second substrate in regions which face the columnar spacers;

wherein the plurality of spacer reception portions include contact reception portions which are in contact with the columnar spacers and concave non-contact reception portions which are not in contact with the columnar spacers,

wherein the concave non-contact reception portions include a first concave non-contact reception portion having a first depth and a second concave non-contact reception portion having a second depth that is different from the first depth, and

wherein the contact reception portions and the non-contact reception portions are alternately arranged in a checkerboard pattern.

2. The liquid crystal device according to claim 1 , wherein the sum of the cross-sectional areas of the columnar spacers which face the concave non-contact reception portions is larger than that of the cross-sectional areas of the columnar spacers which face the contact reception portions.

3. The liquid crystal device according to claim 1 , wherein the cross-sectional areas of the columnar spacers which face the concave non-contact reception portions are larger than those of the columnar spacers which face the contact reception portions.

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