Abstract

In the micro-lens array substrate of the present invention, a micro-lens array formed of a plurality of consecutive concave lens-shaped micro-lenses is directly formed in a surface of a quartz substrate or glass substrate, and the micro-lens array is formed by a transfer method based on dry-etching. In the micro-lens array substrate of the present invention, a taper portion is formed toward the surface of the substrate in a peripheral portion of the micro-lens array in the quartz substrate or glass substrate.
