摘要： In a liquid crystal display device, light transmitting through a liquid crystal layer is colored depending on the structural conditions of the liquid crystal display device. The phase of the transmission light is corrected by means of a phase correction plate to make the transmission light approximate achromatic color, thereby permitting monochromatic display or color display.

摘要： A data converting system converts CRT display data into display data for another display unit such as a liquid crystal display unit by use of a memory. The system includes a data load controller which selects one segment of data out of two segments of data in the CRT display data successively while changing the segment position to be selected alternately in every two frame scanning periods so that the CRT display data for one complete picture is written into the memory in two frame scanning periods, i.e., a segment is written into the memory once for every two adjacent segments. Display data is read out of the memory in the data form conformable to the other display unit.

摘要： A liquid crystal display device comprises: a liquid crystal module including liquid crystal display panel having a plurality of liquid crystal picture elements arranged in a matrix form, and driving circuits for applying driving signals to signal electrodes and to scanning electrodes of the liquid crystal display panel, respectively; a control circuit for controlling operations of the liquid crystal module; and a means for inverting polarity of a voltage to be applied to a liquid crystal layer by generating a control signal M' having a period m.tau. which signal inverts the polarity of the voltage to be applied to the liquid crystal layer whenever a clock signal having a period .tau. is counted a predetermined number m/2. However, if a period of a frame frequency is n.tau. and an arbitrary integer is L,(1) m is set to be 2n/(2L-1), or(2) m is set to be n/L and the control signal M' is inverted per said frame period n.tau., or(3) m is set to satisfy L-1/2

摘要： A liquid crystal display element is produced by forming an electrical insulating metal oxide film on a transparent glass substrate, forming a transparent conductive film thereon by coating a coating solution prepared by diluting a solute comprising indium, tin, a .beta.-diketone and nitric acid with an organic solvent, followed by calcination, etching the transparent conductive film to give electrodes having desired patterns, placing the two resulting glass substrates in parallel so that individual electrodes at the inner side stand opposite to each other, and enclosing a liquid crystal material in the space formed between the two glass substrates. The liquid crystal display element thus produced has transparent electrodes which have low sheet resistance, enhanced mechanical strength and strong adhesive strength to the glass substrate.
