Abstract: Disclosed are a display panel in which a unit pixel is divided into a wide-angle area and a narrow-angle area in which at least sub-pixel is disposed and light emission is individually and selectively performed, a display device including the same, and a manufacturing method thereof. A semi-cylindrical lens is disposed in the wide-angle area so as to cover a plurality of sub-pixels. Semi-spherical lenses are disposed in the narrow-angle area so as to cover sub-pixels respectively. Therefore, a direction of light emitting from a light-emitting layer is controlled by adjusting a refractive index of each of the lenses in the wide-angle area and the narrow-angle area. Thus, a viewing angle is controlled.

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.

Abstract: An organic light emitting display device can include an organic light emitting diode (OLED), a driving transistor connected to an anode electrode of the OLED, a scan transistor, a digital-to-analog converter (DAC) and a sensing unit. The scan transistor is connected the anode electrode of the OLED and a data line. The DAC supplies a data voltage for displaying to the data line in a displaying period and supplies a data voltage for sensing to the data line in a sensing period. The sensing unit obtains an anode voltage of the OLED as a sensing voltage through the data line in the sensing period.
