ABSTRACT:
An optoelectronic panel is disclosed wherein the liquid crystal device and the photo detecting device are formed on a common transparent substrate. The liquid crystal display device includes at least one liquid crystal element which is supplied with a drive signal via a non-single-crystal semiconductor diode serving as a non-linear element and a photo diode of the same structure as the non-single-crystal semiconductor diode serving as the non-linear element of the liquid crystal display device. The liquid crystal display device and the photo detecting device are disposed side by side on the transparent substrate. The liquid crystal element, the non-linear element, the non-single-crystal element and the non-single-crystal semiconductor diode, as the non-linear element, of the liquid crystal display device are formed adjacent one another on the transparent substrate. The one electrode of the liquid crystal element and the one electrode of the non-single-crystal semiconductor diode, serving as the photo diode are both formed on the transparent substrate and are transparent. The one electrode of the non-single-crystal semiconductor diode serving as the non-linear element is also formed on the transparent first substrate but is nontransparent.
