Abstract:
1. An image display device, comprising: a display area which includes a plurality of pixels each of which includes a self light-emitting element; and a plurality of signal lines for inputting an image voltage to each of the plurality of pixels, wherein: each of the plurality of pixels includes a field-effect transistor for driving the self light-emitting element based on the image voltage which is input through each of the plurality of signal lines to each of the plurality of pixels; the display area is divided into at least two regions including a first region, which is configured of a first group of the plurality of pixels to comprise a still image display region, and a second region, which is configured of a second group of the plurality of pixels to comprise a video image display region, in a plane view so that the first group and second group of pixels do not overlap one another; a ratio of a channel width to a channel length (channel width/channel length) of the field-effect transistors in the first region is smaller than the ratio of a channel width to a channel length of any field-effect transistor in the second region, the first region of the display area comprises a plurality of selection switch lines for inputting a selection voltage to each of the plurality of pixels; each of the plurality of pixels in the first region comprises: the selection switch element is controlled to be turned on and off based on the selection voltage which is input through each of the plurality of selection switch lines to each of the plurality of pixels; the second region of the display area comprises a plurality of reset lines for inputting a reset voltage to each of the plurality of pixels; and the reset switch element is controlled to be turned on and off based on the reset voltage which is input through each of the plurality of reset lines to each of the plurality of pixels.
