PIXEL, DISPLAY DEVICE INCLUDING SAME, AND METHOD FOR MANUFACTURING DISPLAY DEVICE

WIPO Patent Application WO/2020/091165

A1

A pixel may comprise: a light emitting element; a first transistor connected between a first node and the light emitting element to control the amount of current flowing from a first actuating power source of the first node to the second actuating power source through the light emitting element; a second transistor connected between a data line and the first transistor, and turned on by an i-th (i is a natural number of 2 or larger) scan signal; a third transistor connected between the first transistor and the first node, and turned on by the i-th scan signal; and a fourth transistor connected between the first node and an initialization power supply line to which initialization power is applied, and turned on by an (i-1)-th scan signal. The fourth transistor may be configured to be a tunnel field-effect transistor comprising: a source region and a drain region spaced a predetermined gap from each other and formed in opposite conductivity types; a channel region provided between the source region and the drain region; and a gate electrode provided above the channel region while a gate insulating layer is disposed between the gate electrode and the channel region.
