Description of the Related Art In recent years, liquid crystal panels have been used not only in displays of portable computers but also in various electronic devices such as displays of desktop computers, televisions, and displays of portable terminals. A general liquid crystal panel has a structure in which liquid crystal is sealed between two transparent substrates. Of the two surfaces of the transparent substrate facing each other, a counter electrode, a color filter, an alignment film, and the like are formed on one surface side, and a TFT (Thin Film Transistor) and a pixel are formed on the other surface side. An electrode, an alignment film, and the like are formed. A polarizing plate is attached to a surface of the transparent substrate opposite to the opposite surface. These two polarizing plates are arranged, for example, so that the polarization axes are orthogonal to each other. When no voltage is applied between the pixel electrode and the counter electrode, light is transmitted and a bright display is performed, and a voltage is applied. In this state, light is shielded and dark display is performed. When the polarization axes of the two polarizing plates are arranged in parallel to each other, dark display is performed when no voltage is applied between the pixel electrode and the counter electrode, and bright display is performed when a voltage is applied.

When the terminal receiving portion 12 is damaged, only the terminal receiving portion 12 can be easily replaced. Therefore, there is an advantage that the maintenance cost can be reduced. The above-described support 10 can also be used when the terminals of the liquid crystal panel 30 and the drive circuit are TAB-connected. In this case, the terminals are heated to a temperature of about 130 ° C. when the liquid crystal panel 30 and the TAB lead of the drive circuit are crimped. The temperature of the part 12 increases. For this reason, the terminal portion of the liquid crystal panel 30 placed on the support base 10 may thermally expand, and it may not be possible to align the terminals of the liquid crystal panel 30 with the TAB leads. However, the liquid crystal panel support 10 of the present embodiment has a large surface area and a high cooling efficiency because the terminal receiving portion 12 has a comb-like unevenness. In addition, as shown in the schematic diagram of FIG. 6, an air pipe 13 is disposed near the terminal receiving portion 12,
By blowing air from the air nozzle 14 provided in the air pipe 13 to the terminal receiving portion 12, the terminal receiving portion 12 can be cooled more efficiently. In addition, a cooling fan may be provided instead of arranging the air pipe 13 and the air nozzle 14, and a cooling pipe through which cooling water passes may be provided in the terminal receiving portion 12.

れを防止することができる。Further, according to the method of supporting a liquid crystal panel of the present invention, a support base having a terminal receiving portion provided with unevenness that partially contacts a terminal portion of the liquid crystal panel is used, and the liquid crystal panel is mounted on the support base. After the contact, the liquid crystal panel is relatively moved in a direction parallel to the upper surface of the support base, so that the foreign substances existing between the liquid crystal panel and the upper surface of the support base move to the concave portions of the terminal receiving portions and are moved to the liquid crystal panel. It is removed from the contact surface with the support. Thereby, it is possible to prevent the liquid crystal panel from being cracked during the lighting test or the TAB connection.
