摘要： PROBLEM TO BE SOLVED: To provide a liquid crystal device which reduces transmission light in a dark state by reducing scattering light caused by the depolarization of linearly polarized light made incident on a color filter layer and improves performance of the liquid crystal device. SOLUTION: A color ferroelectric liquid crystal device is provided with a ferroelectric liquid crystal material 2 between two glass substrates 3, 4 arranged at a fixed interval by spacers. The color filter layer 5 is provided to the glass substrate 3, and the surface of the color filter layer 5 is covered with a flattening layer 6 made of a material which flattens the surface. Electrode structures 7, 8, barrier layers 9, 10 and alignment layers 11, 12 are provided to the surfaces inside the glass substrates 3, 4. Further, in order to reduce the transmission light in the dark state by suppressing depolarization of the light linearly polarized by a polarizer 14 by the color filter layer 5, a polarizing layer 16 is arranged between the color filter layer 5 and the liquid crystal material 2.

摘要： PROBLEM TO BE SOLVED: To reduce the heating of a liquid crystal device and a decrease in display contrast. SOLUTION: A liquid crystal devices is multiplex driven by scanning signals which are imparted sequentially to electrodes 14a..., together with data signals imparted to electrodes 16a.... The first and second sets of electrodes specify a plurality of picture elements. A pattern to be shown the device determines a waveform imparted to the electrode 16a..., the waveform being variable between both of extreme frequencies, i.e., a high frequency matching the same condition of the picture elements and a low frequency matching the conditions of the picture elements which vary alternately between adjacent lines. This adversely affects the performance of the device, particularly in terms of contrast. To solve and improve such a problem, a line driver 18 outputs a scan signal obtained by adding a low frequency signal to a scan signal including known strobe pulses. The low frequency signal reduces the effect of each extreme data signal frequency on the picture elements.
