Title: Image display drive apparatus

Abstract: An image display drive apparatus capable of shifting an image signal in the unit of one pixel in the horizontal direction of a display device such as a liquid crystal device whose plurality of pixels are driven at the same time. The image display drive apparatus for driving a plurality of pixels at the same time includes a signal processing circuit for supplying a plurality of pixel signals at the same time, delay circuits for delaying at least one of the plurality of pixel signals supplied from the signal processing circuit, and selectors for selecting image signals for driving pixels of the display device at the same time, from the outputs of the signal processing circuit and delay circuits, in accordance with a value of a select signal. In the image display drive apparatus, the signal processing circuit, delay circuits, and selectors are interconnected so that an image signal to the left by one pixel is selected as the select signal is incremented by 1.
