Problems solved by technology

If ultraviolet rays are irradiated onto the substrate through the cover box and the upper space where the cover box is not formed, the sealant may be cured before it reaches the attaching device, preventing the lower and upper substrates from being fully bonded

Embodiment Construction

[0033] Embodiments of the present invention, examples of which are shown in the accompanying drawings, will now be described in detail.

[0034] FIG. 2 shows the layout of a production line for LCD devices according to the first embodiment of the present invention.

[0035] As shown in FIG. 2 , a lower substrate having a thin film transistor (TFT) and a pixel electrode is mounted on the first loading device 100 , and a liquid crystal layer is formed on the lower substrate in the liquid crystal distribution device 140 . Then, the lower substrate is mounted on the first buffer 150 .

[0036] The upper substrate having a light shielding layer, a color filter layer and a common electrode is loaded onto the second loading device 200, and a sealant is formed on the upper substrate in a sealant forming device 220. Then, the upper substrate is mounted on the second buffer 250 .

[0037] The lower and upper substrates are moved to an attaching device 300, and they are attached to eac...

Abstract

A production line for manufacture of a LCD device having a plurality of processing devices includes a production line shield being formed of a UV blocking material and positioned along a sealant forming device and an attaching device and between the sealant forming device and the attaching a device; and at least one work lamp that irradiates light in a band other than an ultraviolet band. A UV blocking lamp may be provided above the production line shield. Thus, a sealant is not prematurely hardened, so that the lower substrate is effectively bonded to the upper substrate, and a desired cell gap is maintained between the lower and upper substrates.

Description

[0001] This application claims the benefit of Korean Application No. P2002-11922 filed March 6, 2002, which is incorporated herein by reference in its entirety. technical field [0002] The invention relates to a production line for manufacturing liquid crystal display (LCD) devices, in particular to a production line for LCD devices based on a liquid crystal distribution method. Background technique [0003] In general, ultra-thin flat panel displays having a display screen thinner of several centimeters or less, especially flat liquid crystal display devices, have been widely used for notebook computers, monitors of aircrafts and airplanes because of low driving voltage and easy loading. [0004] This LCD device includes a lower substrate, an upper substrate and a liquid crystal layer. A thin film transistor (TFT) and a pixel electrode are formed on the lower substrate. A light shielding layer, a color filter layer and a common electrode are formed on the upper substrate ...
