摘要： The curing, by UV-light irradiation, of a sealing resin after injecting liquid crystal is made reliable. The display characteristics and the like of an in-plane electric field mode liquid crystal element are improved. To resolve these problems, the viscosity of the sealing resin is lowered, while bubbles mixed in the sealing resin are eliminated by ultrasonic waves, for example. Also, a means for eliminating ions and charges in the liquid crystal layer is devised.

摘要： In a liquid crystal panel in which pseudo dot inversion driving is performed, the occurrence of flicker or vertical and horizontal strings is prevented by preventing an alignment shift between individual layers during the fabrication of a TFT array from producing a difference between the respective abilities of thin-film TFTs to charge adjacent pixels (61, 62). For this purpose, the liquid crystal display panel is constructed such that two TFTs which are enclosed by two adjacent image signal lines (21, 22) and scan signal lines (3) and adjacent to each other along the signal lines (21, 22) have respective source electrodes (71, 72) adjacent to the different image signal lines (21, 22). The source electrodes (71, 72) and drain electrodes (81, 82) of the two TFTs connected to the adjacent pixels (61, 62) are alternately arranged such that variations caused by the alignment shift in the sizes and areas of overlapping portions between the individual layers of the TFTs are equal or the same.

摘要： One of a pair of substrates with liquid crystals sandwiched therebetween includes a plurality of pixels each of which is provided with a scanning electrode, an image signal electrode, a switching element provided at an intersection of the scanning electrode and the image signal electrode, a pixel electrode connected to the image signal electrode via the switching element, a counter electrode, and a busbar electrically connected to the counter electrode. A portion of the pixel electrode is overlapped with the busbar so as to make up a storage capacitance. A shape of the pixel electrode is altered for each pixel so that a value of the storage capacitance becomes smaller from a feeding side to a termination side. The portion of the pixel electrode overlapped with the busbar so as to make up the storage capacitance is located within the busbar in a plan view of the device.
