Abstract

The invention provides a liquid crystal display device which makes it possible to increase functionality by mounting a function element without having to externally mount the function element onto an area near and outside of a liquid crystal display panel. A liquid crystal display device includes a plurality of pixels disposed in a matrix form and a drive element to drive the pixels. A function element, having a function that is different from the function of the drive element, is disposed in an area including the plurality of pixels and used to display. By this, it is possible to increase functionality because function elements having various functions can be incorporated inside a panel.
