<p>PROBLEM TO BE SOLVED: To improve a view angle so that a normal picture is visible from various angles without increasing the manufacturing process and cost by providing a first gradation voltage generator, a second gradation voltage generator and an analog distributor. SOLUTION: The design is performed so that a distribution of a gradation voltage is adjusted properly, and a view angle distribution is obtained, and the first gradation voltage generator 301 is adjusted so that the picture is visualized clearly viewing from the upper side of the picture, and the second gradation voltage generator 302 is adjusted so that the picture is visualized clearly viewing from the lower side of the picture, and when the gradation voltage applied to the upper side and lower side is changed at a fixed period according to an external control signal, the gradation voltage of the first gradation voltage generator 301 and the gradation voltage of the second gradation voltage generator 302 are applied respectively, and the gradation voltage having two view angles different from each other are inputted in mosaic arrangement when a panel 34 is viewed. Thus, an eye of a human viewing the whole picture feels so as to become wide by that the upper/lower view angles are added by an average characteristic of light.</p> |
