Abstract
A substrate is provided for an electro-optical device comprising a substrate, a base layer formed on the substrate and having a plurality of concave portions or convex portions on the surface thereof, and a reflecting layer formed on the base layer and having light reflecting property, wherein a plurality of concave portions or convex portions is formed so as not to extend to the edge of the base layer. According to this construction, a surface provided with concavo-convex portions is spaced apart from the edge of the base layer. Therefore, the sidewall surface that forms the edge is substantially flat. As a result, the base layer does not peel from the substrate when developing the photosensitive material which becomes the base layer.
