摘要

A display apparatus in which selection circuits and display blocks are arranged is provided. Each of the display blocks include signal lines extending in a column direction, and pixels connected to the signal lines and arranged in a matrix in the column direction and in a row direction crossing the column direction. Each of the selection circuits selects a signal line in a predetermined order to supply an image signal among the signal lines such that the image signal is written in each of the pixels arranged in the row direction among the pixels. A time to select at least one signal line among the signal lines and supply the image signal is different from a time to select a signal line other than the at least one signal line among the signal lines and supply the image signal.

In addition, as shown in FIG. 5, in one horizontal scanning period in which the image signals are supplied to the pixels 110 arranged on one row among the plurality of pixel 110, the time to select the signal line 124 (the signal line 124 connected to the pixel R1) that is selected first among the plurality of signal lines 124 may be longer than the time to select the signal line 124 (the signal line 124 connected to the pixel R2) that is the second signal line selected among the plurality of signal lines 124. That is, in the arrangement shown in FIG. 5, the selection circuit 200 prolongs the time to supply the image signal to the signal line 124 connected to the pixels R1 in the first column. This is because a case in which the difference between a reset voltage Vres that is a signal voltage held at the time of reset of the signal generation unit 202 and the signal voltage Vr1 of the first column is larger than the voltage difference between the signal voltages of the adjacent pixels 110 of the same emission color is taken into consideration.
