Abstract
There is provided a display device including: a light emitting element; and a drive transistor (DRTr) that includes a coupling section (W1) and a plurality of channel sections (CH) coupled in series through the coupling section (W1), wherein the drive transistor (DRTr) is configured to supply a drive current to the light emitting element.
Claims22
A display device comprising:
- a plurality of pixels, at least one of the plurality of pixels including a light emitting element;
- a capacitor;
- a write transistor configured to supply a pixel voltage supplied from a data line to the capacitor;
- and
- a drive transistor configured to supply a drive current from a power supply line to the light emitting element according to a voltage stored in the capacitor,
- wherein the drive transistor includes a first channel, a first gate, a first source/drain electrically connected to the power supply line via a first contact, and a second source/drain electrically connected to an anode of the light emitting element via a second contact,
- wherein, in a region where the drive transistor is disposed, an electrically-conductive layer is electrically connected to the power supply line and is arranged over a substrate, a first insulating layer is arranged between the electrically-conductive layer and the first channel, and a second insulating layer is arranged between the first channel and at least a portion of the first gate in a stacking direction,
- wherein the first channel includes a portion of a first silicon layer,
- wherein the electrically-conductive layer encompasses, in a plan view, a first region that includes a second region including the first gate and a third region including the first channel,
- wherein the first contact and the second contact are arranged in a fourth region different from the first region in the plan view, and
- wherein the write transistor includes a second channel that is part of a second silicon layer that is distinct from the first silicon layer.
