Abstract:
1. A display device comprising: a pixel portion comprising a plurality of current supply lines and a plurality of pixels arranged in matrix, each of a first pixel and a second pixel in a first column among the plurality of pixels comprising a first EL element and a first TFT, wherein one of a source and a drain of the first TFT is directly connected to a first current supply line among the plurality of current supply lines and the other of the source and the drain of the first TFT is directly connected to the first EL element, each of a third pixel and a fourth pixel in a second column among the plurality of pixels comprising a second EL element and a second TFT, wherein one of a source and a drain of the second TFT is directly connected to a second current supply line among the plurality of current supply lines and the other of the source and the drain of the second TFT is directly connected to the second EL element; multiple current supply paths for supplying a current from an FPC connecting terminal to the pixel portion, the multiple current supply paths being each directly connected to a different portion of each of the first current supply line and the second current supply line; and a switch for selecting at least one of the multiple current supply paths to supply the current to the pixel portion, wherein the pixel portion is configured to display an image by controlling a light emission state of each of the first pixel, the second pixel, the third pixel and the fourth pixel, wherein the multiple current supply paths are electrically connected to a same power supply through the switch such that a same voltage is applied to the multiple current supply paths, and wherein the multiple current supply paths and the switch are arranged outside the pixel portion.
