BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and method for manufacturing a liquid crystal display device, and more particularly, to manufacturing a liquid crystal display device capable of simultaneously performing a title process for patterning a glass ID and a panel ID using a laser and an ambient exposure process for exposing the outer glass. An apparatus and method are provided.

In general, a liquid crystal display (LCD) displays an image corresponding to a video signal on a liquid crystal panel in which liquid crystal cells are arranged in a matrix form by adjusting light transmittance of liquid crystal cells according to a video signal. To this end, the liquid crystal display device includes an active region in which liquid crystal cells are arranged in an active matrix and driving circuits for driving liquid crystal cells in the active region.

A typical liquid crystal display device includes: a top plate composed of a black matrix, a color filter, a common electrode, and an alignment layer sequentially formed on an upper substrate; A lower plate composed of a TFT sequentially formed on the lower substrate, a pixel electrode and an alignment layer; A spacer formed between the upper plate and the lower plate, and a liquid crystal (not shown) injected into a space between the upper plate and the lower plate.

The lower TFT includes a gate electrode protruding from the gate line, a source electrode protruding from the data line, and a drain electrode connected to the pixel electrode through the contact hole. The TFT further includes a gate insulating film for insulating the gate electrode, the source electrode and the drain electrode, and a semiconductor layer for forming a conductive channel between the source electrode and the drain electrode by a gate voltage supplied to the gate electrode. Such TFT selectively supplies the data signal from the data line to the pixel electrode in response to the gate signal from the gate line. The liquid crystal rotates by the voltage difference between the data signal supplied through the TFT and the common voltage Vcom supplied to the common electrode, and the light transmittance is determined according to the degree of rotation of the liquid crystal. The pixel electrode is positioned in a cell region divided by a data line and a gate line and is made of a transparent conductive material having high light transmittance. The pixel electrode is formed on the passivation layer applied to the entire lower substrate, and is electrically connected to the drain electrode through the contact hole formed in the passivation layer. After the alignment layer is coated on the lower substrate on which the pixel electrode is formed, a rubbing process is performed to complete the lower plate.

The top plate forms a black matrix corresponding to the TFT formation region on the upper substrate to prepare a cell region where a color filter is to be formed. The black matrix prevents light leakage and enhances contrast by absorbing external light. The color filter is formed in the area separated by the black matrix. The color filter selectively transmits light of a specific wavelength to realize R, G, and B colors. The common electrode is supplied with a common voltage Vcom for controlling the movement of the liquid crystal, and the upper plate is completed by performing a rubbing process after forming an alignment layer on the common electrode.

As such, the spherical spacers are dispersed using the spray nozzles on any one of the upper and lower substrates completed through separate processes. Subsequently, the upper and lower plates are bonded to each other, and then the liquid crystal is injected and sealed to complete the liquid crystal display.
