Abstract
In a liquid crystal display device including a display area having a liquid crystal layer between first and second substrates disposed to confront each other, the display area comprising a number of pixels, and an element for driving the liquid crystal layer of each pixel for display being provided on the surface of the first substrate at the liquid crystal layer side of each pixel, in addition to the element, an operating unit for performing predetermined operational processing on the basis of data input to each pixel and outputting the processed data is provided on the surface of the first substrate at the liquid crystal layer side of each pixel. An input register circuit, a memory and an output register circuit may be provided to each pixel. With this structure, the liquid crystal display device has not only the image display function, but also the operating function, whereby the productivity can be enhanced, the manufacturing cost can be reduced and the liquid crystal display device can be designed in compact size and light weight.
