摘要： A liquid crystal display device having a high definition screen in which a pixel electrode is formed in a region surrounded by a gate line and a drain line, and a trapezoidal protrusion having an upper surface and inclined surfaces is formed below the gate line. Since a TFT is formed over a trapezoidal protrusion and a channel portion is formed over the upper surface and the inclined surfaces of the trapezoidal protrusion, the width of the channel portion can be enlarged compared to that of a channel portion formed over a plane. The pixel electrode is in contact with a source electrode at the inclined surface of the trapezoidal protrusion. This configuration allows the TFT and a contact of the pixel electrode and a source electrode to be formed over part of the trapezoidal protrusion.

摘要： A processing portion for conversion from RGB to RGBW includes a W generating circuit, a sub-pixel rendering circuit, a W intensity calculating portion which transmits a W intensity setting value to a W generating circuit, and a low power backlight control circuit which expands data on the basis of the RGBW pixels generated by the sub-pixel rendering portion and lowers the backlight in accordance with the amount by which the data is expanded. The inputted RGB data is used as the RGBW data with the W intensity calculated by the W intensity calculating portion. A backlight control signal is generated based on the amount of data expansion in the sub-pixel rendering portion. Deterioration (darkness) of image quality due to a reduction in the brightness of a single color as a result of the conversion from RGB pixels to RGBW pixels is prevented and a reduction in the power is achieved.
