摘要： An LCD device (1) includes a liquid crystal display panel (2) and a liquid crystal driving section (4) for driving the liquid crystal display panel (2) from a region with a lower temperature to a region with a higher temperature in in-screen temperature distribution of the liquid crystal display panel (2) in operation. This configuration allows a scan direction (6) in which the liquid crystal display panel (2) is driven to correspond to temperature distribution direction (8) from a portion with a lower temperature to a portion with a higher temperature. As a result, image quality of images to be displayed by the general-purpose liquid crystal display panel (2) is improved.

摘要： The present invention is a system, wherein a switching element is on/off controlled by means of a gate driver of a second substrate, electrical conductivity is made to a pixel electrode at a necessary position by means of a reference signal line, and data signals are applied to the data electrodes of a first substrate. An input terminal contact part connected to the drive signal terminal of the gate driver is electrically connected to the signal line contact part on the first substrate side, and the signal line contact part is connected to the first substrate side terminal merging part. Selection of a scanning line by means of the gate driver, and application of the signals to the data electrodes are performed by inputting required signals from the outside to the first substrate side terminal merging part. Because the input terminal contact part is constituted by several connecting lines, electrical connection between the first substrate and the second substrate is not required with respect to the all the scanning lines.
