Patent ID: 8836906

Claim:
A display device comprising: a display section comprising: a first portion of a first substrate; a first portion of an insulating layer over the first portion of the first substrate; a liquid crystal element over the first portion of the insulating layer; and a first portion of a second substrate over the liquid crystal element, and a sensor section comprising: a second portion of the first substrate; a light receiving element over the second portion of the first substrate; a second portion of the insulating layer over the light receiving element; and a spacer over the second portion of the insulating layer, wherein the liquid crystal element comprises a first electrode, a liquid crystal layer over the first electrode, and a second electrode over the liquid crystal layer, wherein the liquid crystal layer comprises a liquid crystal and a polymer, wherein the liquid crystal is dispersed in the polymer, wherein the spacer is capable of transmitting a light, wherein the spacer and the light receiving element are overlapped with each other, wherein the spacer comprises a region where the spacer and the liquid crystal layer are not overlapped with each other in a direction normal to a surface of the first substrate, and wherein the liquid crystal layer is in contact with a side surface of the spacer.
