    摘要: In a display device according to a first aspect of the invention, luminance is not made substantially uniform over the entire display screen but rather imparted a luminance gradient such that luminance substantially monotonously decreases from the center of the screen towards the peripheral portion using a luminance gradient forming means, whereby power consumption is reduced compared to cases in which the entire screen shows substantially uniform luminance. In a second aspect of the invention, by optimizing gray level characteristics and thereby improving a viewer's impression of brightness, luminance gradient is made even less perceivable without increasing power consumption. These configurations provide large screen, low power consumption display devices.

    摘要: A driving method for a spatial light modulator can provide bright image, images of high contrast and resolution with no persistence and instability, and can be used in a projection display system. The spatial light modulator is prepared by sandwiching a ferroelectric liquid crystal layer between a first substrate and a second substrate. The first substrate is prepared by sequentially laminating a transparent conductive electrode and a photoconductive layer with rectifying properties on a glass substrate. On the photoconductive layer, a reflective layer and an alignment layer for aligning a liquid crystal layer are then laminated. The second substrate is prepared by laminating a transparent conductive electrode and an alignment layer on a glass substrate. Alternating current voltage having a waveform of inconsistent cycles is applied to a section between the transparent conductive electrodes.
