Abstract
A display device in which a plurality of pixels are arranged in an array is provided. Each of the plurality of pixels comprises a current path that includes a light emitting element and a first transistor, and a second transistor for transmitting a luminance signal. The first transistor comprises diffusion regions arranged in the current path, and a gate electrode to which the luminance signal is transmitted from the second transistor. The diffusion regions are of a first conductivity type, and the gate electrode is of a second conductivity type opposite to the first conductivity type.

A display device comprising:
- a silicon substrate;
- and
- a plurality of pixels arranged in an array,
- wherein each of the plurality of pixels comprises:
- a current path that includes a light emitting element and a first transistor;
- a second transistor for transmitting a luminance signal;
- and a reset transistor for shorting between terminals of the light emitting element,
- wherein the first transistor comprises (1) diffusion regions arranged in the current path, (2) a channel region arranged between the diffusion regions, and (3) a gate electrode to which the luminance signal is transmitted from the second transistor,
- wherein the diffusion regions of the first transistor are of a first conductivity type,
- wherein the gate electrode of the first transistor is of a second conductivity type opposite to the first conductivity type,
- wherein the diffusion regions of the first transistor are provided in a well of the silicon substrate, the well having the second conductivity type,
