Abstract: In the first signal writing period which is a portion of one horizontal scan period, a first pixel signal is input to the first signal line. The first pixel signal is input from the first signal line to a first pixel circuit throughout a first signal converging period which is longer than the first signal writing period. A second pixel signal is input to the second signal line in a second signal writing period which is another portion of the one horizontal scan period. The second pixel signal is input from the second signal line to a second pixel circuit throughout a second signal converging period which is longer than the second signal writing period. After the first signal converging period and the second signal converging period, electric currents are supplied to the light emitting elements of the first pixel circuit and of the second pixel circuit.

Abstract: Disclosed is a display device capable of achieving a high definition imaging without depending on micronization of display cells. The display device includes: a display panel in which display cells capable of being independently driven are two-dimensionally arranged; and a drive circuit that decomposes an original image that includes plural pixels into plural sub-sampling images that include the pixels which are respectively intermittent in a row direction and a column direction, and sequentially displays the plural sub-sampling images on the display panel. The drive circuit drives a display cell group including plural display cells that are two-dimensionally arranged to be adjacent to each other, corresponding to the respective pixels. The display cell groups respectively corresponding to two arbitrary sub-sampling images are overlapped and are disposed to be mutually shifted.
