1. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a light-domain defect repairing device for repairing liquid crystal gf method and prior-domain defects. [Previous technology] A matrix liquid crystal display device under development includes a first glass substrate, a second glass substrate, and a liquid crystal interposed between the first glass substrate and the first glass substrate. An alignment layer layer) is formed on one surface of each glass substrate (the surface is facing the liquid crystal), and a polarizing plate is on the other surface. The first glass substrate is an array substrate, and individual lines (scanning lines) and scanning lines are formed in a matrix. The surface of the first glass substrate is opposite to the liquid crystal. At the intersection of each individual line and scanning line, there is an image point electrode and a thin film transistor for charging and discharging. The second glass substrate is a color filter and a color layer A colored layer, a protective coat, and a transparent conductive film (conductive fi 1 m) are formed on the surface of the second glass substrate and oppose the liquid crystal.

Therefore, the backlight from the backlight ^ ^ = position: the polarizers at the highest and lowest parts of the LCD display are blocked, while the 2: j face is black. In other words, when no voltage is applied between the liquid crystal and the column substrate and the color filter, the liquid crystal will be along the width of each of the alignment layers :: partial column. 4 The aurora from the backlight's white light is rotated through the liquid crystal by 9 ° = 乂 through the front panel. The aurora passes through a color filter to produce three RGB colors, so the entire LCD display appears white. Parallel and vertical are the same: 1: m External signal generators pass to the thin-film transistor.

-Case No. 91120460 V. Description of the invention (9) (width 3 00 / zmx length !!)!) # !!!) The image point is scanned, controlled to expand or shrink according to the scanning position. Controlling the pulse energy of the laser beam when scanning the alignment layer can achieve satisfactory results by changing the length of the laser beam, especially using a longer laser beam, lower energy and shorter high energy, reducing In the liquid crystal panel, heat affects the radiation from the laser beam because the energy is higher for longer lasers than for short lasers. In terms of thermal effects, the pulse energy is corrected by a linear function and more strictly by a third function. ° ', the direction of the middle V-shaped groove is orthogonal, and 0 is eliminated. According to the first embodiment of the present invention, the alignment layer is irradiated with radiation and the pulsating laser radiation comes from the Q-switching pulsating laser vibrator 2 while using the pulsating laser The radiation from the vibrator 2 causes the radiation to scan the entire layer and may cause them to overlap, and the scanning alignment grooves so that the area of the alignment layer is irradiated with radiation and the kinematic laser. Shooting == Vibrator 2. Under normal circumstances, if the laser beam is used to irradiate the alignment layer to eliminate the angle of aligning the grooves in the alignment layer, the laser beam remains tracked and a new angle is provided to the alignment layer, thereby reducing the effectiveness of laser beam repair. In the first embodiment of the Maoming, the tracking and alignment layer of the laser beam remains. Therefore, the angle of the alignment layer can be more effectively taken.
