Claim 0:
1. A display device, comprising:
a display panel comprising a pixel, the pixel comprising:
a light emitting diode;
a capacitor connected between a first voltage line and a reference node;
a first transistor connected between the first voltage line and a first electrode of the light emitting diode;
a second transistor connected between a data line and a source of the first transistor;
a third transistor connected between the reference node and a drain of the first transistor;
a fourth transistor connected between the reference node and a second voltage line;
a fifth transistor connected between the first voltage line and the source of the first transistor;
a sixth transistor connected between the first electrode of the light emitting diode and the drain of the first transistor; and
a seventh transistor connected between the second voltage line and the first electrode of the light emitting diode, at least one of the third transistor and the fourth transistor comprising:
an active area comprising a metal oxide;
a gate disposed above the active area; and
a first pattern comprising polysilicon, disposed under the active area, and overlapping the active area when viewed in a plan view, wherein the first pattern of the fourth transistor extends from the first pattern of the third transistor.
