Embodiment Construction

[0038] Embodiments of the present invention will be described below with reference to the accompanying drawings. Hereinafter, components that have appeared in the conventional examples described above are denoted by the same reference numerals, and detailed descriptions thereof are omitted.

[0039] As shown in FIG. 1, in a liquid crystal display device embodying the present invention, a nonconductive thin film 14 made of resin such as acrylic resin is arranged on the transparent electrode 5 at a part near the edge of the CF side transparent electrode 5. . That is, the CF side transparent electrode 5 remains up to the CF breakage faces, and the non-conductive thin film 14 is arranged in a region extending from the frame 4 to the CF breakage faces. This prevents leakage due to foreign matter or electrolytic corrosion due to moisture or the like between the CF side transparent electrode 5 and the array side substrate opposite to where the electrode is exposed. Furthermore, eve...

Abstract

The present invention provides a liquid crystal display apparatus which comprises a color filter; and a transparent electrode arranged corresponding to the color filter and extending to the fracture surface of the color surface; wherein, in the region from the frame extending to the fracture surface, a non-conductive film is arranged on the transparent electrode. After the transparent electrode is vapor-deposited over the entire color filter side surface, the non-conductive film is laid where the presence of the transparent electrode causes problems. That is, the non-conductive film is formed of the same material and at the same time as an alignment regulation film over the whole or a part of the area where exposure of the transparent electrode causes problems so as to seal the transparent electrode there. This makes the apparatus possible to prevent the above-mentioned problems caused when the transparent electrode is vapor-deposited over the entire surface, and simultaneously to enhance the patterning accuracy up to the exposure accuracy (of the order of several mum) of proximity or the like so as to realize a product with a narrow frame.

Description

[0001] This application claims priority to Patent Applications Nos. 2003-329358 and 2004-198880 filed in Japan on September 22, 2003 and July 6, 2004, respectively, the entire contents of which are hereby incorporated by reference . technical field [0002] The present invention relates to a liquid crystal display device such as a liquid crystal display. In particular, the present invention relates to the structure of a color filter used in a liquid crystal display device. Background technique [0003] In recent years, since liquid crystal displays (LCDs) have advantages such as light weight, thinness, low power consumption, low-voltage driving, and minimal influence on the human body, the range of applications of liquid crystal displays (LCDs) has rapidly expanded. Among these liquid crystal displays, color liquid crystal displays continue to remarkably increase their applications as they are increasingly used for color display in personal computers and various devices for...
