Abstract
An opposing substrate as a substrate for an electro-optical device includes a transparent base member and a light shielding portion disposed on a region between pixels on the base member. The light shielding portion includes a first reflective film and a second reflective film that is disposed to overlap the first reflective film and has a reflection rate lower than that of the first reflective film, and a first protective film that covers the first reflective film is provided between the first reflective film and the second reflective film.
Claims12
A substrate for an electro-optical device including a plurality of pixels comprising:
- a base member;
- a color filter corresponding to a pixel among the plurality of pixels over the base member;
- a first metal layer disposed between the base member and the color filter, the first metal layer including aluminum;
- a second metal layer disposed between the base member and the first metal layer by overlapping the first metal layer, the second metal layer including titanium;
- and
- a protective film disposed between the first metal layer and the second metal layer, the protective film being directly in contact with each of the first metal layer and the second metal layer.
