1. An apparatus comprising a plurality of pixels arranged in an array on a substrate, the plurality of pixels each including a light emitting element, a first transistor, and a second transistor, one of main terminals of the first transistor being connected to an anode of the light emitting element, and one of main terminals of the second transistor being connected to a control terminal of the first transistor,
wherein the one of main terminals of the second transistor that is connected to the control terminal of the first transistor includes a first region, a second region located between the first region and a channel region of the second transistor and a fifth region located between the second region and the channel region of the second transistor,
wherein another of main terminals of the second transistor includes a third region and a fourth region located between the third region and the channel region of the second transistor,
wherein the first and third regions are made of a semiconductor-metal compound,
wherein the second and fourth regions are made of a semiconductor,
wherein in a plan view perpendicular to the substrate, a length of a current path from the first region to a control terminal of the second transistor is greater than a length of a current path from the third region to the control terminal of the second transistor, and
wherein a resistivity of the fifth region is higher than a resistivity of the second region.
