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.
