A display device includes: a display element including a plurality of sub-elements connected to retention capacities, respectively; a plurality of writing transistors arranged corresponding to the sub-elements, respectively, and writing an image signal to the retention capacities; and a plurality of driving transistors driving the sub-elements, respectively based on the image signal written through the writing transistors. The writing transistors, the driving transistors or both of them are aligned along a source-drain alignment direction in which a drain electrode and a source electrode of each transistor in the writing transistors and driving transistors are aligned, and the writing transistors, the driving transistors or both of them are arranged so that drain electrodes or source electrodes in a pair of transistors are immediately adjacent to each other, the pair of transistors being a pair of the writing transistors or the driving transistors, and being immediately adjacent to each other.
