Display device with threshold correction

Abstract

A display device comprises a first pixel circuit and a second pixel circuit adjacent to the first pixel circuit along a first direction. The first pixel circuit includes a first transistor and a first electro-optic element, and the second pixel circuit includes a second transistor and a second electro-optic element. A power supply line extends along the first direction. A connection wiring is connected between the first transistor and the second transistor, and is connected to the power supply line via a contact portion having at least two contact holes.
