Abstract: A display device optimized to operate in a low frame rate mode under certain predetermined conditions is provided. To reduce pixel discharge during the low frame rate mode, the display device employees the TFTs with metal oxide semiconductor layer, the optical alignment layer with an upper portion and a lower portion having different resistivity. In addition, a passivation layer is provided between the optical alignment layer and the pixel or the common electrode for compensating the low resistivity of the lower portion of the optical alignment layer. As such, various visual defects associated with the pixel discharge can be reduced even when the display device is operating under the low frame rate mode.
