Problems solved by technology

[0027] Second, since the second substrate has no operational action when the sealant is applied and the liquid crystal is dripped on the first substrate, the manufacturing process between the first and second substrates is unbalanced, which leads to a decrease in the working efficiency of the production line
[0028] Third, since the sealant is applied and the liquid crystal is dripped on the first substrate, the first substrate coated with the sealant cannot be cleaned by an ultrasonic cleaner (USC)
[0032] Poor alignment of liquid crystals can cause stains such as scratches and brightness-related stains

Embodiment Construction

[0071] Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Figures 2A-2F The shown cross-sectional views schematically illustrate the steps of a method of manufacturing an LCD according to a preferred embodiment of the present invention.

[0072] see Figure 2A , the liquid crystal 12 is dropped on the first glass substrate 11 , and the sealant 14 is applied on the second substrate 13 . A plurality of panels are designed on one of the first and second glass substrates 11 and 13, and a thin film transistor array is arranged on each of these panels. A plurality of panels are designed on another glass substrate corresponding to the aforementioned panel, and a color filter array having a black matrix layer, a color filter layer, and a common electrode are arranged on each of these panels. For convenience of explanation, the substrate with the thin film transistor array is called the ...

Abstract

A method for fabricating an LCD includes the steps of (a) loading a first substrate and a second substrate having seals formed thereon on a bonding chamber, (b) bonding the first and second substrates, (c) fixing the bonded first and second substrates, and (d) unloading the fixed first and second substrates.

Description

[0001] This application claims the benefit of Korean Application No. P2002-9096 filed on February 20, 2002 and Korean Application No. P2002-10170 filed on February 26, 2002, which are hereby incorporated by reference. technical field [0002] The invention relates to a liquid crystal display, in particular to a method for manufacturing a liquid crystal display by adopting a liquid crystal dropping method. Background technique [0003] In general, demand for various types of display devices has increased due to recent technological developments in the information communication field. According to this demand, the industry has developed various flat panel displays such as liquid crystal display (LCD), plasma display (PDP), electroluminescence display (ELD), vacuum fluorescent display (VFD), some of which have been used as various The device's display. [0004] LCDs have been widely used as mobile displays, and LCDs have replaced CRTs (cathode ray tubes) due to their features ...
