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.

A photosensitive resin applied onto a substrate is exposed using a mask. In this exposure step, by appropriately setting the size of each light transmitting portion formed in the mask and an exposure gap, an exposure intensity profile on a surface of a photosensitive resin is formed so as to have an increasing and decreasing curve along the surface thereof. When the exposure is performed in accordance with the exposure intensity profile, followed by development, a resin layer having surface irregularities is formed. Subsequently, a reflection layer made of a metal thin film or the like is formed on this resin layer.
