Display device

A display device comprising:

• a display area including a pixel array part including at least one terminal;
• a connection area disposed on a back side of the display area and including a connection terminal part to which a signal is supplied from outside;
• and
• a bending area connecting the display area with the connection area and including a first connection line and a second connection line that are disposed between the pixel array part and the connection terminal part, wherein
• the pixel array part includes a transistor including a semiconductor layer, a first layer on the semiconductor layer, a gate electrode on the first layer, a second layer on the gate electrode, a source electrode on the second layer, and a drain electrode on the second layer,
• the first connection line includes a first wiring on the first layer and a second wiring on the second layer, the first wiring being disposed obliquely and leftward to an extending direction of the first connection line and the second connection line, the second wiring being disposed obliquely and rightward to the extending direction and connected to the first wiring,
• the second connection line includes a third wiring on the first layer and a fourth wiring on the second layer, the third wiring being disposed obliquely and leftward to the extending direction of the first connection line and the second connection line, the fourth wiring being disposed obliquely and rightward to the extending direction and connected to the third wiring,
• the first wiring and the third wiring are formed of a same layer as the gate electrode,
• the second wiring and the fourth wiring are formed of a same layer as the source electrode,
• the first wiring of the first connection line and the fourth wiring of the second connection line are disposed so as to intersect with each other,
• in plan view, the first wiring of the first connection line and the fourth wiring of the second connection line are overlapped each other, and
• the first wiring of the first connection line and the fourth wiring of the second connection line are separated from each other so that a predetermined insulation layer is disposed between the first wiring of the first connection line and the fourth wiring of the second connection line.
