Patent ID: 6992832

Claim:
A method of producing a liquid crystal display device having a panel structure including: a first substrate having the front surface on which at least pixel electrodes and switching devices for driving said pixel electrodes are formed and the back surface opposed to the front surface; a second substrate having the front surface on which at least a counter electrode is formed and the back surface opposed to the front surface; and a liquid crystal layer interposed between said first and second substrates joined such that said pixel electrodes are opposed to said counter electrode with a specific gap kept therebetween; wherein a first microlens array composed of two-dimensionally arrayed microlenses for individually condensing light to said pixel electrodes is integrally formed on one of said first and second substrates; and a second microlens array composed of two-dimensionally arrayed microlenses for allowing light individually condensed to said pixel electrodes to pass therethrough is integrally formed on the other of said first and second substrates; said method comprising: a bonding step of bonding a base plate to the front surface of each of said first and second substrates; a polishing step of polishing the back surface of each substrate in a state that each substrate is held by said base plate, to reduce the thickness of each substrate; a sticking step of sticking the corresponding one of said first and second microlens arrays tote polished back surface of each respective substrate via a transparent optical resin having a refractive index higher or lower than that of said substrate; and a peeling step of peeling said base plate from the front surface of each substrate and cleaning each substrate, thereby integrating said coresponding microlens array to the back surface of each substrate, and further wherein the first optical resin layer is made from a UV-cure type resin having a low refractive index.
