no. 1 approach

[0029] The first embodiment of the present invention shows a first configuration example of a liquid crystal display panel in which the outflow of a liquid crystal material can be prevented by making the pattern width of the corner pattern wider than that of other patterns other than the corner pattern.

[0030] 1( a ) and FIG. 1( b ) are diagrams schematically showing the shape of a seal pattern for liquid crystal sealing according to the first embodiment of the present invention. Overall plan view of the pattern; FIG. 1( b ) is a plan view enlargedly showing a corner pattern of the seal pattern for liquid crystal sealing in FIG. 1( a ). Here, for convenience of description, the direction of the seal pattern for liquid crystal sealing is shown as shown in the figure. In addition, in Figure 1 with Figure 7 The same reference numerals denote the same or corresponding parts.

Abstract

A liquid crystal display panel of the present invention is as follows. For example, in a liquid crystal display panel (L) in which an active matrix substrate (1) and an opposing substrate (2) are bonded with each other by a liquid crystal-sealing seal pattern (7) interposed therebetween and the liquid crystal-sealing seal pattern (7) is arranged so as to surround a liquid crystal layer-region (9), the pattern width (W2) of corner patterns (18b) to (21b) and (22b) to (23b) is substantially wider than the pattern width (W) of transversal patterns (11) to (14) and longitudinal patterns (15) to (17).

Description

technical field [0001] The present invention relates to a liquid crystal display panel used in a liquid crystal display device. Background technique [0002] In recent years, it is necessary to suppress the power consumption of these image devices and make them light and thin in terms of image display devices mounted on image devices such as information equipment such as personal computers or image devices such as car navigation systems. Liquid crystal display devices are widely used. [0003] The liquid crystal display device is configured to include: for example, a liquid crystal display panel that changes the transmittance of light according to an input driving signal to display an image; an illuminating unit that is arranged behind the liquid crystal display device and is used to provide light to the liquid crystal display device; Circuit boards and the like for driving liquid crystal display devices. [0004] Figure 6 It is a cross-sectional view schematically showin...
