Embodiment Construction

[0094] based on Figure 1 to Figure 12 One embodiment of the present invention is explained as follows.

[0095] like figure 2 As shown, the main part of the liquid crystal display device of this embodiment is constituted by the liquid crystal display panel 10 as the display panel and the drive circuit section. In the liquid crystal display panel 10 described above, a liquid crystal composition is held between a pair of electrode substrates, and a polarizing plate is attached to the outer surface of each electrode substrate.

[0096] In a TFT (Thin Film Transistor: thin film transistor) array substrate as one electrode substrate, a plurality of signal lines S(1), S(2), ... S(i), ... on a transparent insulating substrate 1 such as glass S(N) and scanning signal lines G(1), G(2), ... G(j), ... G(M) form a matrix. Furthermore, at the intersections of these signal lines and scanning signal lines, TFT 2 as a switching element connected to the pixel electrode 3 is formed, and an...

Abstract

A display apparatus comprises a liquid crystal display panel and a scan signal line drive circuit for outputting a scan signal to the scan signal lines. The liquid crystal display panel includes a plurality of video signal lines for supplying a data signal, a plurality of scan signal lines provided by intersecting the video signal lines, and a pixel electrode provided through a switching element at each of the intersections between the video signal lines and the scan signal lines. The display apparatus further comprises a slope generation circuit (50) for generating a falling slope signal for controlling, based on the signal delay transfer characteristics of the scan signal lines depending on the length of the liquid crystal display panel, the scan signal so as to fall with a substantially identical slope regardless of the position on the scan signal line and outputting the falling slope signal to the scan signal line drive circuit (20). The slope generation circuit (50) includes an EEPROM (52) for variably setting the rising and falling times of the scan signal.

Description

technical field [0001] The present invention relates to a display device including a display panel and a scanning signal line driving circuit that outputs scanning signals to scanning signal lines. Background technique [0002] Liquid crystal display devices are widely used as display elements such as televisions and graphic displays. Among them, in particular, a liquid crystal display device in which a switching element such as a thin film transistor (Thin Film Transistor, hereinafter referred to as TFT) is provided for each display pixel can obtain a good display image without crosstalk between adjacent display pixels even if the number of display pixels increases. , so it has received special attention. [0003] like Figure 13 As shown, the main part of such a liquid crystal display device is composed of a liquid crystal display panel 110 and a driving circuit unit. The liquid crystal display panel 110 is composed of a liquid crystal composition sandwiched between a pa...
