Problems solved by technology

For example, gravity defects can be caused if excess liquid crystals are dispensed on the LCD panel
Or, if there are not enough liquid crystals, it will cause poor display quality
Complete failure of the LCD panel may occur if an excessive amount of liquid crystal is dispensed on the LCD panel and the LCD panel is kept at high temperature

Abstract

An LCD device and a repairing method thereof to prevent gravity defects by forming a dual seal pattern in a non-display area of an LCD panel and storing surplus liquid crystal in an area between the dual seal patterns, which includes an LCD panel including first and second substrates bonded to each other and having a display and non-display areas, first and second seal patterns spaced apart from each other in the non-display area and surrounding the display area to define a buffer space therebetween, and a metal pattern formed on the first substrate corresponding to the first seal pattern. In the method, the metal pattern is heat treated to form a path for surplus liquid crystal to flow to the buffer space.

Description

[0001] This application claims the benefit of Korean Application P2004-22961 filed Apr. 2, 2004, which is incorporated herein by reference. technical field [0002] The present invention relates to a liquid crystal display (LCD) device, in particular, the present invention relates to a liquid crystal display (LCD) device and a method for storing excess liquid crystal by forming a double seal pattern in a non-display area of ​​an LCD panel and storing excess liquid crystal in an area between the double seal patterns. The method for manufacturing and repairing LCD devices avoiding gravity defects. Background technique [0003] The demand for various display devices is increasing with the development of the information society. Accordingly, much work has been done in research and development of various flat panel display devices such as liquid crystal display devices (LCDs), plasma display panels (PDPs), electroluminescent displays (ELDs), and vacuum fluorescent displays (VFDs)...
