Abstract
A display device includes a multilayer passivation structure and has an undercut formed in the passivation structure such that a connection between a cathode and an auxiliary wiring is formed inside the undercut, so as to prevent voltage drop of the cathode and influence of hydrogen on thin film transistors and thus to improve reliability of the display device.
