Abstract
Disclosed herein are a microlens array sheet having a black matrix and a method for manufacturing the same. The manufacturing method includes a) the step of defining the regions of light apertures, through which condensed light passes, in a negative-type light-sensitive resin layer by radiating and condensing parallel light after sequentially laying a microlens array layer, a transparent support substrate or film layer and the negative-type light-sensitive resin layer one on top of another, and b) eliminating portions other than the regions of the light apertures formed in the light-sensitive resin layer, and forming a black matrix layer in regions where the portions have been eliminated.
