ABSTRACT:
The invention provides an electrooptic device which is suitable for use in a portable telephone, a mobile computer, and the like, and in which the effective voltage to be applied to the liquid crystal is high, high-contrast display is possible, and a reflective electrode is prevented from deteriorating. The invention also provides a production method for the electrooptic device. An electrooptic device includes a pair of substrates opposing each other so as to seal and hold liquid crystal therebetween, and a reflective plate that is formed on the side of one of the substrates close to the liquid crystal and that has one or more openings, each at a predetermined position, to reflect incident light from the other substrate and to transmit light from a backlight source. A transparent electrode is formed on the reflective plate, and is electrically connected to a drain electrode or a semiconductor layer.
