摘要： A liquid crystal display device includes: scanning wires, provided so as to correspond to a plurality of pixels disposed in a matrix manner, to which scanning signals are applied; and signal wires to which data signals are applied, wherein the scanning wires and the signal wires cross each other. TFTs, electrically connected to the scanning wires and the signal wires, each of which is provided in the vicinity of an intersection of the scanning wire and the signal wire, and the TFTs are connected to pixel electrodes. A dummy pixel driven by a dummy signal wire is provided externally adjacent to an endmost pixel column.

摘要： In one embodiment of the present invention, a liquid crystal panel driving device for AC-driving a liquid crystal panel with first and second polarities includes an output tone generating section for generating an output tone corresponding to an input tone. With respect to the same input tone, the output tone generating section generates a first output tone when driving the liquid crystal panel with a first polarity, and generates a second output tone when driving the liquid crystal panel with a second polarity. The first and second output tones are determined based on a characteristic of the input tone and the center of amplitude of a voltage to be outputted in response to the input tone in AC driving. This allows providing a liquid crystal panel driving device capable of easily performing Ω correction with respect to each liquid crystal panel.

摘要： Provided is a display device capable of correctly displaying an image when surplus outputs are produced within a driver, regardless of a shifting direction of a shift register within the driver, without bringing about increase in cost and increase in consumption current. A timing controller (200) is provided with a register (22) that can store data indicating the length of a horizontal back porch when a shifting direction of a shift register within a source driver (300) is in a forward direction and data indicating the length of the horizontal back porch when the shifting direction is in an inverse direction. A source-start-pulse generation unit (21) within the timing controller (200) refers to the data within the register (22) according to the shifting direction of the shift register, and generates one of a first source start pulse signal (SSP1) for the forward direction and a second source start pulse signal (SSP2) for the inverse direction.
