摘要:
A high voltage capacitor is disclosed that comprises a grounding member (1), two through type capacitors (2 and 3), an insulating case (6) and insulating resin (71 and 72). The grounding member (1) has two raised portions (101 and 102) on which the through type capacitors (2 and 3) are secured. The insulating case (6) has two hollow cylindrical portions (61, 62) spaced apart by a distance D with their upper open ends joined to each other to form a recessed enclosure (63) in line with and following the inner diameter sections (611, 621) of the hollow cylindrical portions (61, 82) and their lower open ends fitted on the outer circumference of the raised portions (101, 102). The insulating resin (71 and 72) is provided around the through type capacitors (2 and 3) within the inner diameter sections (611, 621). It is thus possible to provide a high voltage capacitor with superior mechanical strength and excellent withstand voltage characteristics even in humid environments and that is small in size and inexpensive.

A display device which transmits display data to drive circuits which drive a display panel using low voltage differential signals have input circuits which are hardly influenced by noise. To transmit the low voltage differential signals under the same condition, low voltage differential signal lines are formed in a zigzag pattern so as to make the lengths of the lines equal. To reduce the influence generated by the overlapping of the zigzagged low voltage differential signal lines and the drive circuits, level shift circuits are provided to the input circuits so as to make the input signals assume a stable operation level.

The present invention realizes a liquid crystal display which mounts driving circuits of low power consumption on a substrate on which a display part is mounted. The driving circuits which supply gray scale voltages to pixels are mounted on a liquid crystal display panel. Display data is transferred between the driving circuits using wiring formed on the liquid crystal display panel, the display data is transferred in the inside of the driving circuits through inner data bus lines, and a data inversion calculation which inverts values of the display data is performed in the inside of the driving circuits for achieving the low power consumption.
