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.

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.
摘要翻译：在根据本发明的第一方面的显示装置中，整个显示屏幕上的亮度不会基本上均匀，而是赋予亮度梯度，使得亮度从屏幕的中心朝向周边部分使用亮度梯度大致单调减小与整个屏幕显示出基本均匀的亮度的情况相比，功耗降低。在本发明的第二方面中，通过优化灰度特性并由此改善观看者的亮度印象，在不增加功率消耗的情况下使亮度梯度更少可感知。这些配置提供了大屏幕，低功耗的显示设备。
