<P>PROBLEM TO BE SOLVED: To keep maintainability by improving relative positioning accuracy of a panel mask while maintaining dust-proof structure and a function such as cleaning performance. <P>SOLUTION: By removing the panel mask 74 and a rubber shield 75 from a mask base 73, a surface of a liquid crystal display device 19 is fully exposed, and can be wiped with solvent. When using the image display device, the mask base 73 and the panel mask 74 integrated by lugs 73a and hooks 74a are fixed to a heat sink 71 after the position thereof is adjusted on the heat sink 71. The rubber shield 75 is attached on the panel mask 74, and a flange part 75a of the rubber shield 75 hermetically seals the space so as to prevent dust from deposing on a light entry/exit surface of the reflective liquid crystal display device 19. <P>COPYRIGHT: (C)2009,JPO&INPIT |
