Embodiment approach 1
[0063] First, refer to Figure 9 , to describe a liquid crystal display device and a method of manufacturing the same according to the first exemplary embodiment of the present invention.
[0064] In general, a liquid crystal display panel has a TFT substrate formed with switching devices such as TFTs arranged in a matrix method, and a CF substrate formed with black matrices, color filters (CF), and the like. Alignment-treated alignment films are formed on the facing surfaces of these substrates. A predetermined gap is defined between the two substrates by arranging insulating spacers such as polymer beads or silica beads of a predetermined shape, or insulating posts of acrylic resin or the like. Such a liquid crystal display panel displays an image by controlling an alignment direction of liquid crystals enclosed in gaps by means of an electric field generated by electrodes formed on at least one substrate.

Embodiment approach 2
[0081] refer to Figure 10 , a liquid crystal display device and a method of manufacturing the same according to the second exemplary embodiment of the present invention will be described.
[0082] Figure 10 is a schematic diagram of a process of manufacturing a liquid crystal display panel according to the present exemplary embodiment, showing an alignment film coating step to a plasma ashing step.
[0083] In the alignment film coating step, in the same manner as in the first exemplary embodiment, printing is performed using an alignment plate to apply an alignment material to the surfaces of the TFT substrate and the CF substrate, thereby giving the display area and the display area The outer area provides an alignment film ( Figure 10 Step A) in .
[0084] In the subsequent temporary drying step of the alignment film, both the display area and the area outside the display area were homogenized at 80°C ( Figure 10 Step B) in .
[0085] In the next alignment film bak...
Embodiment approach 3
[0098] A liquid crystal display device and a manufacturing method thereof according to a third exemplary embodiment of the present invention are described.
[0099] In the same manner as in the above-described second exemplary embodiment, the processes from the application of the alignment film to the baking of the alignment film are performed to provide a desired alignment film in the display area and the area outside the display area.
[0100] In the subsequent plasma ashing step, the surface of each substrate was covered with a mask except for the area outside the display area to allow the alignment film in the area outside the display area to be partially ashed. The entire substrate surface is directly irradiated with plasma by means of a fixed plasma head to form minute holes in the alignment film only in the area outside the display area. Thus, a porous alignment film was formed.
[0101] After that, in the rubbing step, rubbing was performed on the alignment film surface...
