Abstract: A liquid crystal display device carries out tone display with pixels by applying a tone voltage according to tone data to each pixel in each frame, and includes: an LUT memory, which receives tone data of a display frame and tone data of an immediately preceding frame, for converting and outputting the tone data of the display frame; a source driver for applying the tone voltage to the pixels based on the converted tone data outputted from the LUT memory; and a liquid crystal cell, which makes up the pixels, for realizing tone display by the applied tone voltage, wherein the LUT memory stores beforehand output tone data which is specified by the tone data of the display frame and the tone data of the immediately preceding frame. This reduces a voltage change of pixel electrodes which is associated with a tone change to suppress unmatched tone display, thereby improving image quality of moving images.

Abstract: An electrode is provided on one surface of each of a pair of substrates. On the other surface of each of the substrates, a polarizer is provided.

Abstract: On one of surfaces of each substrate, an electrode is provided. Then, alignment films, which have been subjected to rubbing treatment, are provided on the respective electrodes so that the alignment films covers the respective electrodes. Moreover, on the other one of the surfaces of each substrate, a polarizer is provided so that its absorption axial direction matches with a rubbing direction of the corresponding alignment film. The substrates face each other so that the rubbing directions of the alignment films respectively provided on the substrates cross each other perpendicularly. A medium having a negative type liquid crystalline property is sealed between the substrates so as to form a material layer. In this way, it is possible to improve contrast and to alleviate coloring phenomenon in a display element in which transmittance is changed by controlling orientational order of molecules.

Abstract: While image data is written into either one of first, second, third frame memories 1, 2 and 3, image data are repetitively read two times from the remaining two memories in one vertical synchronization interval and transferred to an arithmetic unit 4, and this operation is executed with the frame memories changed sequentially. An arithmetic unit 4 refers to a look-up table on the basis of two inputted data values and, when the data value of the current image signal is greater than the data value of the previous image signal, the unit 4 transfers image data of a value greater than the data value of the current image signal to a liquid crystal display device 5. Thus, the step response characteristic is improved for the improvement of the dynamic image display quality.
