ABSTRACT:
A display device having an electromagnetic field preventing and protecting circuit having a separated structure for enabling easy repairing in case abnormal characteristics are generated by static electricity at electrostatic prevention circuit for protecting the display device from static electricity. An electromagnetic field preventing and protecting circuit of a display device includes a separated structure in a charge input line which couples an input terminal of a power supply voltage line or a cathode supply voltage line to the electromagnetic field preventing and protecting circuit. The separated structure is formed such that the electromagnetic field preventing and protecting circuit can be easily separated The separated structure may include a circuit separation part having a narrower width compared to the rest of the charge input line, and the electromagnetic field preventing and protecting circuit may include a diode ring.
