Abstract
An element substrate is formed as a lens array substrate on which a plurality of lenses are formed. In a method of manufacturing the lens array substrate, first recess sections are formed on one surface of the substrate, and then a plurality of lens surfaces, which include concave surfaces, are formed at the bottoms of the first recess sections 195. Subsequently, after a light-transmitting lens layer is formed to fill the inside of the first recess sections, flattening is performed while the lens layer is removed. Here, the surface of the lens layer on a side opposite to the substrate is a planar surface which is contiguous to an outside area that is positioned on the outer side of the first recess sections on the one surface of the substrate.
