Display device
View Patent ↗An inspection circuit is properly protected in a display device, which the driver IC is not on the terminal area. A liquid crystal display device comprising a TFT substrate having a display area, in which video signal lines are formed, and a terminal area; a counter substrate overlapping with the display area of the TFT substrate; the counter substrate and the TFT substrate are adhered by the seal material, the display area is formed in an area surrounded by the seal material; wherein the flexible wiring circuit substrate connects to the terminal area, the driver IC, which supplies video signals to the video signal lines, is not installed in the terminal area, the inspection circuit is formed between the display area and the terminal area, wherein the inspection circuit overlaps with the counter substrate in a plan view.
1. An organic EL display device comprising:
a TFT substrate having a display area, in which video signal lines are formed, and a terminal area;
wherein an anode is formed on a first organic insulating film, an organic EL layer is formed on the anode, a cathode is formed on the organic EL layer, an inorganic insulating film is formed on the cathode, and a polarizing plate is set on the inorganic insulating film,
a plurality of first terminals to connect with a flexible wiring circuit substrate and a plurality of second terminals utilized in an inspection process are formed in the terminal area,
an inspection circuit is formed between the display area and the terminal area in a plan view in the TFT substrate,
the inspection circuit has a plurality of switching portions to connect the video signal line to either one of the first terminals or one of the second terminals,
the first organic insulating film is formed on the inspection circuit at a surface opposing to the polarizing plate.
2. The organic EL display device according to claim 1 ,
wherein the inspection circuit further overlaps with the inorganic insulating film in a plan view.
3. The organic EL display device according to claim 1 ,
wherein a second organic insulating film is formed between the first organic insulating film and the inorganic insulating film,
the second organic insulating film overlaps with a periphery of the anode in a plan view.
