摘要： A transmission type display includes a thin film transistor for driving a pixel electrode, which transistor is provided on a substrate, and a conductive shield layer provided at a position over the thin film transistor and under the pixel electrode. A first planarization film is formed to bury an irregular contour of the thin film transistor and the shield layer is disposed on the planarized surface of the first planarization film, and a second planarization film is formed to bury steps of the shield layer, and the pixel electrode is disposed on the planarized surface of the second planarization film. Since the transmission type display has the structure in which the conductive shield layer is put between the upper second planarization film and the lower first planarization film each of which is made from an insulating material, the shielding performance and the alignment characteristic of the display can be improved.

摘要： A transmissive display device includes a driving substrate positioned on a emergent side which has both a group of pixels including component units each having a pixel electrode and a switching device, and a black matrix for shielding light from reaching the non-aperture part of each pixel from the incident side. The black matrix has an overlaid structure formed by overlaying a low-reflection metallic layer and a high-reflection metallic layer with an interlayer insulating film provided therebetween. Both layers are patterned, and partially overlap with each other as mutually complement to shield incident light. When observed in plan view from the incident side, the exposing area of the low-reflection layer is enlarged, while the exposing area of the high-reflection metallic layer is reduced to suppress the surface reflectance of the black matrix. Thereby, multiple reflection inside liquid crystal does not occur, and it is possible to prevent contrast deterioration caused by leaked rays.

摘要： A synthetic quartz glass substrate (1) supporting active elements is formed of high-purity synthetic quartz glass having, a hydroxyl group content of 200 ppm or below and chlorine group content of 50 ppm or below. The substrate (1) may have an impurity level of 1 ppm or less sodium and 1 ppm or less aluminum. TFTs (6), i.e., active elements, and picture element electrodes (7) are formed on the surface of the synthetic quartz glass substrate (1) to construct a driving panel for a liquid crystal display of an active matrix type. A liquid crystal panel is formed by disposing the driving panel and a counter substrate (2) opposite to each other and sandwiching a liquid crystal layer (3) between the driving panel and the counter substrate (2).
