Embodiment Construction

[0029] Preferred embodiments of the active matrix liquid crystal display device of the present invention will be described based on the embodiments.

[0030] (first implementation)

[0031] will first refer to Figures 3 to 9 An active matrix liquid crystal display device and a manufacturing method thereof according to a first embodiment of the present invention will be described.

[0032] Such as image 3 As shown in , the active matrix liquid crystal display device 100 includes a TFT substrate 51 in which switching elements (such as TFTs) are formed and an opposite substrate 52 disposed facing the TFT substrate 51 . These substrates are bonded together with a sealing material 30 . A liquid crystal material (not shown) is placed in the area surrounded by the sealing material 30 . The TFT substrate 51 includes a display area in which pixels are formed in a matrix, and circuit units such as a horizontal driver 43 and a vertical driver 44 for driving the pixels. Furthermore,...

Abstract

Active matrix display device includes connection wirings passing through a sealing material. The connection wirings are sandwiched between inorganic interlayer insulation film and an organic planarizing film. The organic film is selectively removed at a seal region to form opening portions to expose the inorganic film and to be filled with a sealing material. The sealing material contacts the lower layer inorganic interlayer insulation film in the bottom of an opening portion to increase the adhesive strength.

Description

technical field [0001] The invention relates to an active matrix display device and a manufacturing method thereof. More specifically, the present invention relates to a thin film transistor array substrate constituting an active matrix display device and a manufacturing method thereof. Background technique [0002] In recent years, active matrix liquid crystal display devices are widely used as high-resolution displays, and thin film transistors (TFTs) are used as switching elements of pixels in the active matrix liquid crystal display devices. An example of such an active matrix liquid crystal display is disclosed in, for example, Japanese Laid-Open Patent No. Hei06-258661. This conventional active matrix liquid crystal display device using TFTs will be described with reference to FIGS. 1 and 2 . FIG. 1 is a schematic perspective view showing the general configuration of a conventional active matrix liquid crystal display device. FIG. 2 is a cross-sectional view showing...
