Abstract
In the display apparatus, a gate driver receives at least one clock to sequentially provide gate lines in a display panel with a gate signal in a high state corresponding to a high interval of the clock. The gate driver includes a plurality of amorphous silicon transistors and is formed in the display panel through a thin film process. The clock has a delay time of about 2.0 μs or less. If the delay time of the clock is reduced less than about 2.0 μs, a threshold voltage margin of the transistors increases, so that the gate driver may not malfunction in a high temperature aging process. As a result, the gate driver may be prevented from malfunctioning in the high temperature aging process.
