Abstract
A display device having at least a plurality of pixel circuits, connected to signal lines to which data signals in accordance with luminance information are supplied, arranged in a matrix, wherein pixel circuits of odd number columns and even number columns adjacent sandwiching an axis in a column direction parallel to an arrangement direction of the signal lines have a mirror type circuit arrangement symmetric about the axis of the column direction, and there are lines different from the signal lines between signal lines of adjacent pixel circuits.
