ABSTRACT:
A display device such as a liquid crystal display device is provided which comprises a single substrate, a plurality of thin film semiconductor elements provided on the substrate, a plurality of display elements whose pixel display is controlled by the semiconductor elements, and electrodes for driving the display elements. The substrate includes a display zone having the thin film semiconductor elements arranged in the display elements as well as a non-display zone. The non-display zone has a display scan drive circuit area and a display signal drive circuit area. The thin film semiconductor elements are formed in the both zones. A distance between the display signal drive circuit area and the semiconductor elements of the display zone on the substrate is physically arranged so as be larger than a distance between the display scan drive circuit area and the semiconductor elements of the display zone. In the display device, the multiplicity of semiconductor elements are formed on a glass substrate having one side of several or more inches so that minimum processing dimensions of the semiconductor elements in the display zone are smaller than those in the non-display zone.
