Liquid crystal display device

A display device, comprising:

• an image display region comprising a plurality of pixels defined by a plurality of scanning signal lines and a plurality of video signal lines;
• a plurality of blocks, each of which includes a plurality of selection TFTs formed outside the image display region, each selection TFT having a gate electrode, a source electrode, and a drain electrode connected to a corresponding one of the plurality of scanning signal lines, each of the selection TFTs in one of the blocks having a corresponding selection TFT in the other blocks;
• a plurality of scanning connection lines formed outside the image display region, each scanning connection line connected to all source electrodes of the plurality of selection TFTs included in a corresponding one of the plurality of blocks;
• a plurality of selection signal lines, each of which is connected to the gate electrodes of one set of the corresponding selection TFTs in the plurality of blocks, the corresponding selection TFTs that are connected to one of the plurality of selection signal lines being different from the corresponding selection TFTs that are connected to the other of the plurality of selection signal lines;
• a scanning signal drive circuit providing selection signals to the plurality of selection signal lines, respectively, and applying on-voltages to the plurality of scanning connection lines, respectively;
• and
• an insulating film interposed between the gate electrodes of the plurality of selection TFTs and the selection signal lines,
• wherein the gate electrodes of the plurality of selection TFTs and the selection signal lines overlap with each other in plan view, respectively, and
• the gate electrodes of the plurality of selection TFTs and the selection signal lines are connected to each other via holes formed through the insulating film, respectively.
