Abstract

The invention provides an electro-optical device and an electronic device for restraining bad influence to display image caused by light leakage and light reflection of peripheral area without deterioration of transistor characteristics in the electro-optical device of LED device. The electro-optical device is on the substrate(10), comprising a plurality of pixel electrodes(9a), a transistor(71) provided in the peripheral area surrounding the pixel area(10a) with a plurality of pixel electrodes, a light-shielding film(510) arranged below the transistor, at least partially overlapping with thetransistor in plan view from the substrate and having a rectangular opening(510s) that extends in the channel length direction of the transistor.

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] In such an electro-optical device, a plurality of scanning lines and data lines arranged vertically and horizontally in a display area composed of a plurality of pixels, and a plurality of pixel electrodes corresponding to their intersections are provided on a TFT substrate. Such an electro-optical device generally adopts an active matrix driving method driven by TFT (Thin Film Transistor, Thin Film Transistor), for example, and a TFT for pixel switching is provided corresponding to each pixel. The image signal supplied to the data line is supplied to the pixel electrode according to the switching operation of the pixel switching TFT formed in each pixel, and an image is displayed in the display area. In addition...
