Claim Text:
1. A display device, which is an active matrix display device using an organic EL (electroluminescence) panel, comprising: a plurality of pixel circuits each including an organic light emitting diode arranged in a pixel region of the organic EL panel and a plurality of transistors configured to drive the organic light emitting diode, the pixel circuits of at least one set of the pixel circuits being adjacent in a first direction; a plurality of scanning lines arranged along the first direction in the organic EL panel; and a plurality of data lines arranged along a second direction that is orthogonal to the first direction in the organic EL panel, wherein gate electrodes and impurity diffusion regions of the plurality of transistors have an axisymmetric layout in the at least one set of pixel circuits, gate electrodes of at least one set of transistors that are symmetrically arranged in the at least one set of pixel circuits are integrated, the integrated gate electrodes of the at least one set of transistors that are symmetrically arranged in the at least one set of pixel circuits that are adjacent in the first direction are connected to a single line at one connection point, the connection point being at a center of the gate electrodes, and in the first direction, the integrated gate electrodes form a mirror image about the connection point.
