Abstract:
An object of the present invention is to provide a pixel structure capable of shielding light between a TFT and a pixel without using a light shielding mask (black matrix) in an electro-optical display device. The present invention has a feature in that, as one of means for shielding light, a lamination film consisting of two colored layers (a lamination layer of a red-colored layer and a blue-colored layer) is formed on an opposing substrate as a light shielding portion so as to overlap with a TFT formed on a device electrode.
