    • Picture element electrodes (7) are electrically connected with drain electrodes (18D) of respective transistor elements (18). The picture element electrodes (7) and data signal lines (SLn, SLn+1, . . . ) are provided above scanning signal lines (GLn, GLn+1, . . . ). The picture element electrodes (7) overlap scanning signal lines (GLn, GLn+1, . . . ) when viewed from above. Notch parts 7a and 7b are provided in each picture element electrode (7) so as to overlap each of the scanning signal lines (GLn, GLn+1, . . . ). Shield electrodes (4a, 4b) are formed in the same layer as the data signal lines (SLn, SLn+1, . . . ). Each of the scanning signal lines (GLn, GLn+1, . . . ) at least partially overlaps the shield electrodes (4a, 4b) in the notch parts (7a, 7b), when viewed from above. This provides the liquid crystal display panel having wide viewing angle characteristic and carrying out high quality display.

    • An LUT fixedly stores correction values to compensate for a pull-in voltage in pixels in a liquid crystal panel. In at least one example embodiment, the display control unit outputs an input video signal Xa, a video signal Xp of a previous frame read from a frame memory, and a pixel polarity indicating a polarity of a pixel applied voltage on the pixel basis, and outputs a correction value read from the LUT to a data line driving circuit as a video signal Xb after correction. The data line driving circuit performs alternate current driving, based on the video signal Xb after correction. The LUT stores different correction values between when a positive polarity voltage is applied and when a negative polarity voltage is applied, for at least a part of combinations of values of the input video signal Xa and the video signal Xp of the previous frame. This can reduce a difference in response speed between when the positive polarity voltage is applied and when the negative polarity voltage is applied, thereby enhancing display quality.
    • LUT固定地存储校正值以补偿液晶面板中的以像素为单位的拉入电压。 在至少一个示例性实施例中,显示控制单元输出输入视频信号Xa,从帧存储器读取的先前帧的视频信号Xp和表示像素基础上的像素施加电压的极性的像素极性,以及 在校正之后将从LUT读取的校正值作为视频信号Xb输出到数据线驱动电路。 数据线驱动电路根据校正后的视频信号Xb进行交流驱动。 对于输入视频信号Xa和前一帧的视频信号Xp的值的组合的至少一部分,LUT存储施加正极性电压和施加负极性电压之间的不同校正值。 这可以减小施加正极性电压时和施加负极性电压之间的响应速度差,从而提高显示质量。
