ABSTRACT:
Disclosed is an image display apparatus having, in every pixel, a light-emitting element such as an organic electro-luminescence (EL) element of which the brightness is controlled by a current. The image display apparatus includes transistors that form a current mirror in the pixel and using a pixel structure having two scan lines, so as to select pixels of at least two rows simultaneously, distribute the current applied to the data line to the pixel for recording display information and the adjacent pixel, and record the display information on the pixel of no more than one row among the selected pixels. This drastically increases the current for driving the data line and decreases the size of the transistors that form the current mirror in the pixel.
