Abstract
An electro-optical device includes, on a TFT array substrate, a data line, a scanning line, a switching element, and a pixel electrode and the like, the substrate having an image display region defined as a region to form the pixel electrode and the switching element, and a peripheral region to define the surrounding area of the image display region, the peripheral region being configured by including a TFT to determine whether the image signal will be applied to the data line, and a light shielding film which is formed via the TFT and the interlayer insulating film, the light shielding film overlapping at least a portion of the TFT in plan view. The electro-optical device is capable of reducing or preventing the breakdown of the switching element and obtaining the precise operation of the switching element by not creating a crack in the interlayer insulating film or the like between the switching element and the light shielding film.
