Patent ID: 7233372

Claim:
An electro-optical device, comprising: a light exit substrate; a counter substrate opposing the light exit substrate; a frame-shaped light shielding layer disposed over the counter substrate and defining an image display region; a display electrode disposed over the light exit substrate within the image display region; a pattern portion disposed over the light exit substrate at a position overlapping with the frame-shaped light shielding layer and within the image display region in plan view, the pattern portion being coupled to the display electrode and including a wiring and a transistor, the transistor including a source and a drain; a lower light shielding layer outside the image display region and in overlap with the frame-shaped light shielding layer in plan view, the lower light shielding layer covering the pattern portion from a light exit side of the light exit substrate, the lower light shielding layer including a drain section confronting the drain of the transistor and a source section confronting the source of the transistor, the drain section and the source section of the lower light shielding layer being island shaped and separated from each other by a gap so that the drain section and the source section are isolated from each other by the gap, the gap being in a non-overlapping condition with the drain and the source in plan view.
