The liquid crystal display device of the invention includes: a first substrate having a first surface, a second surface and at least four side surfaces; a second substrate having a surface opposed to the first surface of the first substrate; a liquid crystal layer interposed between the first surface of the first substrate and the surface of the second substrate; a plurality of pixel electrodes; a plurality of switching elements, each of the switching elements supplying a signal to a corresponding one of the plurality of pixel electrodes; drivers for driving the plurality of switching elements; and a controller for controlling the driver. In the liquid crystal display device, the drivers are provided on the first surface of the first substrate, and the controller is provided above the second surface of the first substrate.
