Latest Patents

Akiyama is associated with 1 patent: “Liquid Crystal Display with Black Matrix Formed by a Black Resin Optical Shielding Layer and a Blue Filter Layer.” The invention describes a display with two substrates and a liquid crystal layer between them. One substrate carries a black matrix, color filter, and counter electrode; the other carries gate and source signal lines, thin-film transistors, and matrix-arranged pixel electrodes.

The black matrix combines a black resin optical shielding layer with a blue filter layer. The described fabrication method forms the blue-filter portion using photoresist containing a blue pigment and patterns it through backside exposure. The design aims to support preferable display images while keeping production costs low and avoiding environmental deterioration during fabrication.
