Abstract:
1. A thin film transistor (TFT) substrate comprising: a substrate; a set of signaling lines formed on the substrate, the signaling lines comprising a data line, a source electrode and a drain electrode; a color filter formed on the substrate in direct contact with the signaling lines, the color filter having at least a first opening defined therethrough; an inorganic insulating layer formed sealingly over the color filter layer including being sealingly formed inside the first opening; a light blocking material formed on the inorganic insulating layer and formed inside of the first opening; a pixel electrode having at least one portion thereof disposed above the inorganic insulating layer and above the light blocking material, where the at least one portion of the pixel electrode covers at least part of an upper surface of the light blocking material, and where the pixel electrode is electrically connected to the drain electrode.
