摘要： A data line driving section (6) outputs a video signal voltage for each pixel to a data line (DL) for each predetermined period in order. In outputting a video signal voltage for a pixel, the data line driving section (6) outputs a gradation signal voltage having a voltage corresponding to a gradation value of the pixel as the video signal voltage during a second part of the predetermined period, and outputs a correction gradation signal voltage different from the gradation signal voltage as the video signal voltage during a first part of the predetermined period. A control section (4) changes a relationship between the correction gradation signal voltage and the gradation signal voltage based on a combination of the gradation value of the pixel and a gradation value of a pixel preceding the pixel.

摘要： A liquid crystal display device includes data lines, a plurality of pixel circuits, and a control circuit which obtains data line potentials which are formed by correcting potentials which allow the respective pixel circuits to display tones. The control circuit obtains the data line potentials such that a correction amount from a first potential to the data line potential when a tone potential in a frame which is displayed is the first potential and a tone potential in a frame right before the frame is a second potential, and a correction amount from the second potential to the data line potential when the tone potential of the frame which is displayed is the second potential and the tone potential of the frame right before the frame is the first potential differ from each other.

摘要： A resistive element (115) is connected in series to a cathode terminal of an LED light source at a last stage (or an anode terminal of an LED light source at a first stage) of an LED chain (116), and the resistive element (115) is configured to be variable in resistance value in accordance with a variation of voltage drops of the LEDs connected in series so that a resistive element connected to an LED chain having a large voltage drop has a small resistance value while a resistive element connected to an LED chain having a small voltage drop has a large resistance value. With this configuration, the power, which has been wasted otherwise as heat in the backlight driver IC, may be dispersed to the resistive elements.
