    Abstract: A display apparatus includes a display panel, a gate driver, a data driver and an emission driver. The display panel includes a pixel. The gate driver is configured to provide a gate signal to the pixel. The data driver is configured to provide a data voltage to the pixel. The emission driver is configured to provide an emission signal to the pixel. The pixel includes a light emitting element, a driving switching element and a bias switching element. The driving switching element is configured to apply a driving current to the light emitting element. The bias switching element is configured to provide a bias voltage to an input electrode of the driving switching element. A frequency of a bias gate signal applied to a control electrode of the bias switching element is greater than a frequency of a data write gate signal applied to the pixel.

    Abstract: A display apparatus is provided including a display area and a non-display area. The display area includes a display element and the non-display area includes a pad portion. A first thin-film transistor (TFT) is arranged in the display area. The first TFT includes silicon and a first gate electrode. A second TFT is arranged on a first insulating layer covering the first gate electrode and includes an oxide and a second gate electrode. A first voltage line extends in a first direction. A data line is spaced apart from the first voltage line. A connection wire is disposed in the display area and connects the data line to the pad portion. The connection wire includes a first portion extending in the first direction and a second portion extending in a second direction crossing the first direction, and the first portion overlaps the first voltage line.
