  • Patent number: 7480098
    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.

  • Patent number: 7268949
    Abstract: A microlens array sheet and a manufacturing method thereof. The microlens array sheet comprises: a transparent substrate; bases formed on the transparent substrate, the bases having the same height as a result of a planarization process conducted for the upper portions of the bases, microlenses formed on the bases; and a gap-filling film applied on the resulting structure, in which the bases have the same height. The method comprises the steps of: depositing base-forming molds on a transparent support substrate or film and loading a material to be used as bases between the base-forming molds; polishing the upper portion of the material for use as bases so as to form bases having the same level, and removing the base-forming molds; depositing microlenses on the formed bases; and depositing a gap-filling film on the resulting structure.
