摘要： To give an electric shield function and an electric contact function to a light shielding film formed on a drive substrate. An active matrix display device includes a drive substrate 1 having pixels 4, an opposed substrate 2 having an opposed electrode 5, and a liquid crystal 3 held in a space defined between the drive substrate 1 and the opposed substrate 2. An upper layer portion of the drive substrate 1 includes pixel electrodes 6 formed individually for the pixels 4. A lower layer portion of the drive substrate 1 includes thin-film transistors 7 for individually driving the pixel electrodes 6, scanning lines 8, and signal lines 9. A light shielding film having conductivity is interposed between the upper layer portion and the lower layer portion, and is divided into mask shielding films 16M and pad shielding films 16P. Each mask shielding film 16M is continuously patterned along each row of the pixels 4 to partially shield at least the corresponding thin-film transistor 7. Each mask shielding film 16M is insulated from both the upper layer portion and the lower layer portion, and is maintained at a fixed potential. The pad shielding films 16P are discretely patterned for the individual pixels 4, and each pad shielding film 16P is located at a contact portion C between the corresponding pixel electrode 6 and the corresponding thin-film transistor 7 to provide electrical connection therebetween and light shielding.

The device is free from the problem of photoelectric current leakage. The device comprises an active substrate with a pixel transistor TFT thereon and a counter substrate that faces the active substrate via liquid crystal therebetween, wherein light-shielding layers (upper light-shielding layer, and lower light-shielding layer) are formed to be adjacent to the side of the pixel transistor part that faces the counter substrate and adjacent to the side thereof that faces opposite to the counter substrate and wherein the upper light-shielding layer and the lead electrode shield the entire region except the pixel openings from the incident rays that enter the device through the counter substrate.

摘要： A transmissive display device includes a driving substrate positioned on the 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 TFT substrate is provided near its outer periphery with a metallic wiring and pad portions, and a conductive light-shielding film is provided on the outside of these. The conductive light-shielding film is left annularly along the outer peripheral portion of the TFT substrate so that, when an upper layer light-shielding film is formed on the TFT substrate, the upper layer light-shielding film on the scribed line side would not easily be exfoliated at the time of etching or cleaning. Of the conductive light-shielding film, the position of the conductive light-shielding film disposed on the outside of the pad portions is shifted to the outer side so that the spacing between the conductive light-shielding film and the pad portions is set to be, for example, not less than 10 &mgr;m. By this, electrostatic trouble between the conductive light-shielding film and the pad portions is restrained.

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.
