1. A display cell comprising:
a signal line electrically connected to a pixel arranged in a display area;
a signal pad unit disposed in a peripheral area adjacent to the display area, and including a signal pad electrically connected to the signal line; and
a power supply voltage line configured to apply a power supply voltage to the pixel, and divided into a plurality of sublines by at least one slit pattern in a cut-off area in the peripheral area,
wherein the power supply voltage line includes at least one of a first power supply voltage line configured to transmit a first power supply voltage to an organic light emitting diode of the pixel, and a second power supply voltage line configured to transmit a second power supply voltage to the organic light emitting diode, and
wherein a width of the at least one slit pattern in an extension direction of a cutting line is greater than a pitch of a laser spot used during a cutting process.
