すことができる。 A chassis 6 is provided at the bottom of the frame 5, drive circuit boards 7...7 are appropriately held on the back surface of the chassis 6, and the LCD panel 1 is mounted via spacers 8...8 that are appropriately arranged around the chassis 6. Installed.
The chassis 6 has two long sides of a rectangular bottom part 9 and peripheral parts 10A, 10B, and 10C provided on one short side, and guide grooves 11A and
11B is formed, a contact surface 12 is formed on the inner surface of the peripheral part of one long side, and an elastically deformable hook 14 is integrally molded in the center of the open side 13 where the peripheral part is not formed. The thin film EL4 is inserted along these guide grooves 11A and 11B, and the hook 14 is hung while it is in contact with the contact surface 12, and the thin film EL4 is
It is fixed to the back of the LCD panel 1. The thin film EL4 can be easily taken out by removing the hook 14.
上記実施例における薄膜EL４に代えて、その

Since the thin light emitter can be replaced by simply removing the hook, there is no need to disassemble the LCD unit, and the process can be done in a short time. Furthermore, since there is no need for screws, springs, or other members for fixing the thin light emitting body, the number of man-hours required for installing them is small, and the unitization is easy.
