METHOD FOR MANUFACTURING MICROLENS SUBSTRATE, MICROLENS SUBSTRATE, COUNTER-SUBSTRATE FOR LIQUID CRYSTAL PANEL, LIQUID CRYSTAL PANEL, AND PROJECTION TYPE DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a microlens substrate which is formed of a resin layer uniform in thickness and inhibits or prevents the presence of residual bubbles from occurring. SOLUTION: The microlens substrate 1 has a glass substrate 2 having a plurality of recessed parts 3 for a microlens and a glass layer 8 joined to a face where the recessed parts 3 are formed of the glass substrate 2, through a resin layer 9. In the resin layer 9, the microlens 4 is formed with a resin packed in the recessed parts 3. The resin layer 9 is formed by curing an uncured resin with a viscosity of 500 cP or less at 25 deg.C, especially an ultraviolet-curable resin. In addition, the index of refraction of the resin layer 9 is preferably 1.35 or more.
