Abstract: A liquid crystal display device includes a first substrate, a second substrate, a liquid crystal layer that is interposed between the first and second substrates, and a sealing member that is formed in peripheral portions of the first and second substrates. The sealing member includes a ring-shaped portion that seals the liquid crystal layer inboard of the sealing member and connecting portions that connect first and second regions of the sealing member to form the ring-shaped portion. The connecting portions are formed outboard of the ring-shaped portion.

Abstract: The invention provides a liquid crystal device that is substantially free from problems, such as deterioration in display contrast by preventing or inhibiting the nonuniformity of the gap between substrates. Since a liquid crystal display device has a structure in which spacers are disposed between a pair of substrates having a liquid crystal layer sandwiched and held therebetween; depressions are formed on the substrate; and the spacers are disposed mainly in the depressions, the gap between the substrates is reliably made more uniform across the surfaces of the substrates. Especially, since the depressions are formed so as to correspond to non-pixel regions, the spacers have less influence on display.

Abstract: To provide a method for manufacturing a liquid crystal display device capable of preventing nozzle clogging and a variation in spacers, and obtaining a liquid crystal display device with high display quality. The method includes an aggregation heating step of heating a substrate to evaporate droplets to the extent that spacers discharged to the substrate aggregate in a predetermined range, and a complete evaporation heating step of further heating the substrate subjected to the aggregation heating step to completely evaporate the droplets. In the aggregation heating step, the substrate is heated to a temperature of 30 to 60° C., and a drying time of 30 seconds is secured for the solvent.

Abstract: A method and circuit for activating a liquid crystal matrix display panel in which during each selecting period, each liquid crystal cell pixel of the matrix, whether selected or unselected, receives either a primary selecting signal voltage or non-selecting signal voltage as well as an additional different secondary voltage to generate substantially homogeneous crosstalk noise over the entire display. The signal voltage applied to a pixel during a selecting period can vary between a primary selecting or non-selecting voltage applied for a first time interval followed by or preceded by a secondary voltage intermediate the selecting and non-selecting voltage applied for a second interval. Alternatively, the primary signal voltage applied to the pixel for a first time interval can be a selecting or non-selecting voltage and secondary voltage applied for a second time interval can be the other.
