Patent ID: 8426228

Claim:
A method of mass producing a plurality of TFT supporting substrates, the method comprising for each TFT supporting substrate: providing a light passing substrate layer having a plurality of pixel areas; forming a set of signal lines on the substrate layer, the set of signal lines comprising a data line, and comprising for each pixel area, a source electrode and a spaced apart drain electrode; forming a semiconductive portion to which the source and drain electrodes are coupled, where a channel portion is defined in the semiconductive portion between the spaced apart source and drain electrodes; forming a color filter layer in direct contact with the signal lines, the color filter layer having for each pixel area, a corresponding first opening defined through the color filter layer and disposed over the corresponding channel portion of the respective pixel area; forming an inorganic insulating layer on the color filter layer to thereby seal the color filter layer, said inorganic insulating layer extending into an interior of each of the first openings of said pixel areas; forming a light blocking material on the inorganic insulating layer, said light blocking material extending into an interior of each of the first openings of said pixel areas and covering the corresponding channel portion; and forming for each pixel area, a pixel electrode disposed on the inorganic insulating layer and on the light blocking material, where the pixel electrode connects electrically to the corresponding drain electrode of the pixel area and where the pixel electrode covers at least a portion of the light blocking material disposed in the interior of the corresponding first opening of the pixel area.
