Abstract:
1. A liquid crystal display device having an area used for display, comprising: a first substrate; a second substrate; a liquid crystal layer between the first and second substrates; a plurality of pixels disposed in a matrix form; a plurality of drive elements formed on the first substrate to drive the pixels; a signal wiring layer formed on the first substrate to drive the pixels; a light-shielding layer formed on the second substrate at a location opposing the drive element; and a function element having a function that is different from a function of the drive elements disposed at a location where the function element overlaps at most two of the plurality of drive elements within the area used for display, the function element being in a non-overlapping condition with others of the drive elements, wherein the function element is disposed on a surface of the second substrate that faces the liquid crystal layer, the function element being formed at a side of the light-shielding layer facing away from the liquid crystals, the function element includes an element selected from a group consisting of an image pick-up element, a memory element, an operating circuit, a temperature correction circuit, a feedback circuit, a photodiode, and a sensor; and an insulating layer separating the light-shielding layer from the second substrate and the function element.
