Abstract
The electro-optical apparatus of the invention has a pair of substrates and an electro-optical material held between these substrates. The TFT array substrate may be formed into a concave shape in non-aperture areas containing the data line, the scanning line, the capacitor line and the TFT. Further, the areas opposite to the connecting lines in the sealed area may be formed into a concave shape. In the electro-optical apparatus having such a configuration, it is possible to reduce steps resulting from the presence of various wiring lines and elements in the image display area and the sealed area, by the use of a relatively simple configuration.
