摘要： A display apparatus includes a voltage generator, a display panel and a panel driving part. The voltage generator includes an operation amplifier including a first input terminal electrically connected to a reference voltage receiving terminal, a second input terminal receiving a feedback common voltage and an output terminal outputting a common voltage generated by comparing a reference voltage received at the reference voltage receiving terminal and the feedback common voltage and a first resistor electrically connected between the second input terminal and the output terminal. The display panel includes a dummy line electrically connected in series between a first connection line and a second connection line, and the dummy line provides the feedback common voltage to the second input terminal through the first connection line. The panel driving part drives the display panel.
