Abstract

An electrooptical device includes a substrate, a pixel electrode which is provided on the substrate, a semiconductor element which is provided so as to correspond to the pixel electrode, and a light reflection portion formed with a groove formed on at least a part of the substrate. In the electrooptical device, the semiconductor element is arranged so as to overlap with the light reflection portion in plan view and is arranged on a flattened film provided so as to cover at least an opening of the groove.

Description

technical field [0001] The present invention relates to the technical field of electro-optical devices such as liquid crystal devices and electronic equipment such as liquid crystal projectors equipped with the electro-optical devices. Background technique [0002] As such an electro-optical device, there is a liquid crystal that is an electro-optical substance sandwiched between a TFT array substrate on which pixel electrodes and pixel switching TFTs (Thin Film Transistors, thin film transistors) are formed, and a counter substrate on which counter electrodes are formed. finished liquid crystal device. In such a liquid crystal device, in order to improve utilization efficiency of incident light incident from the side of the counter substrate, a prism corresponding to each pixel is sometimes incorporated in the counter substrate (for example, see Patent Document 1). [0003] On the other hand, for example, in Patent Document 2, it is disclosed that a groove is formed on a T...
