Problems solved by technology

[0034] However, there is such a problem that the longer the storage line, the larger the resistance and wiring capacitance, so fluctuations in potential occur, thereby causing flicker and gradation of brightness in the displayed image, deteriorating the display quality
[0035] The measure to address these problems is to increase the amount of conductive glue applied, and the coating operation of conductive glue will take some time, which increases the time of the so-called production takt.

Embodiment 5

[0090] In this embodiment, the second columnar conductive spacer is used instead of the Figure 8 Conductive adhesive CPT near middle seal SL. The shape of the second type of columnar spacer is similar to that of the aforementioned columnar conductive spacer (hereinafter referred to as the first type of columnar spacer) disposed in the pixel area, but it is made to have a required cross-sectional area. In this embodiment, voltage is supplied to the common electrode ITO2 without using conductive glue, and manufacturing steps are significantly reduced by simultaneously processing the first type of columnar spacer and the second type of columnar spacer.

[0091] An example of a liquid crystal display device using the liquid crystal display element of the present invention will be described below, including the configuration of its drive circuit and applications of the liquid crystal display device.

[0092] Figure 9 is a block diagram illustrating an exemplary configuration of...

Abstract

A liquid crystal display element includes a pair of substrates, a liquid crystal layer sandwiched therebetween, gate lines and drain lines disposed to intersect the gate lines disposed on one of the substrates, thin film transistors disposed at the intersections of the gate and drain lines, pixel electrodes disposed in an area surrounded by two adjacent gate lines and two adjacent drain lines, a common electrode disposed on the other substrate. The liquid crystal display element is also provided with storage lines disposed below the pixel electrodes with an insulating layer interposed therebetween to form a capacitance therebetween. Each of the pixel electrodes is formed with an opening in a portion thereof facing the storage lines.

Description

technical field [0001] The present invention relates to a liquid crystal display element, in particular, to a thin film transistor active matrix type liquid crystal display element equipped with a storage capacitor formed of a storage line and a pixel electrode disposed therein in a pixel region. Background technique [0002] Liquid crystal display devices are widely used as high-definition color display devices for notebook computers and display monitors. [0003] Among liquid crystal display elements, simple matrix type and active matrix type are common. The simple matrix liquid crystal display element includes: a pair of opposite substrates; a first group of parallel strip electrodes arranged on the inner surface of one of the substrates; a second group of parallel strip electrodes arranged on the inner surface of the other substrate , the set of electrodes intersects the first set of parallel strip electrodes; and a liquid crystal layer sandwiched between the two substr...
