Patent ID: 7480098

Claim:
A method of manufacturing a microlens array sheet having a black matrix layer, comprising the steps of: sequentially depositing a microlens array layer, a transparent support substrate or film layer, and a negative type light sensitive resin layer; radiating the microlens array layer with a parallel light, wherein the microlens array layer focuses the parallel light; forming trapezoidal shaped light aperture regions in the negative-type light sensitive resin layer by exposing the negative-type light sensitive resin layer to the focused light; eliminating non-exposed portions of the negative-type light sensitive resin layer not exposed to the focused light; and forming a black matrix layer in regions where the non-exposed portions have been eliminated, wherein the trapezoidal shaped light aperture regions are formed such that an area through which the focused light enters the negative-type light sensitive resin layer is smaller than an area of the region through which the focused light is emitted from the negative-type light sensitive resin layer.
