Embodiment Construction

[0049] Hereinafter, the present invention will be described by way of schematic examples with reference to the accompanying drawings.

[0050] (Example 1)

[0051] attached Figure 1A It is a schematic perspective view of an active matrix liquid crystal display device 100 . The liquid crystal display device 100 includes a base substrate 110 , a counter substrate 120 and a liquid crystal layer 130 disposed between the base substrate 110 and the counter substrate 120 . The liquid crystal layer 130 includes a liquid crystal material. The base substrate 110 includes a display area 140 and a driving circuit system area 150 . In the driving circuit system area 150, a scan driver 102 and a data driver 103 are disposed. On the base substrate 110 is provided with a pixel electrode (in the attached Figure 1A not shown, but described below). On the counter substrate 120, a counter electrode 160 is disposed on the side facing the pixel electrodes. The liquid crystal layer 130 is c...

Abstract

A liquid crystal display device comprises a base substrate including a display region, a drive circuitry region provided in a surrounding region of the display region, a liquid crystal layer, and a counter substrate facing the base substrate via the liquid crystal layer. A pixel electrode and a pixel driving element for driving the pixel electrode are provided in the display region, a driving circuitry section for controlling the pixel electrode and the pixel driving element is provided in the drive circuitry region. An insulating layer is provided to cover at least one portion of the drive circuitry region. A common transition electrode is provided in the insulating layer. The common transition electrode is electrically connected to a counter electrode provided on the counter substrate.

Description

technical field [0001] The invention relates to a liquid crystal display device including a drive circuit system, the drive circuit system includes an active element and a pixel drive element, and the drive circuit system and the pixel drive element are arranged on the same substrate. More specifically, the present invention relates to a liquid crystal display device in which a common transition electrode is disposed through an insulating layer on a driving circuit region where a driving circuit system is provided. Background technique [0002] As is well known, liquid crystal display devices are used to display images. A liquid crystal display device displays images by controlling voltage applied across a liquid crystal material interposed between a base substrate and a counter substrate. [0003] One type of liquid crystal display device is an active matrix type liquid crystal display device. An active matrix type liquid crystal display device includes a thin film transi...
