NANO-PROJECTOR PANEL FORMED BY ARRAYED LIQUID CRYSTAL CELLS

摘要

PROBLEM TO BE SOLVED: To provide a panel in which MOS control transistors are protected from light.SOLUTION: In the panel formed by arrayed cells and allowed to be used for a nano projector, each cell has a liquid crystal layer surrounded by an upper side transparent electrode and a lower side transparent electrode, a MOS control transistor is arranged on the upper side of the upper side transparent electrode and each MOS control transistor is coated with at least three metal coating layers. The MOS control transistors of respective cells are arranged on the corner parts of the respective cells so that the MOS control transistors of an aggregate consisting of four adjacent cells are arranged on the center part of the aggregate. The upper metal coating layer coats the upper side of the MOS control transistors of the aggregate of the four adjacent cells. The panel comprises a first conductive annular body surrounding the MOS control transistors in each aggregate of four adjacent cells, and the first annular body extends from the lower metal coating layer to the upper side transparent electrodes of respective cells through an insulator.
