摘要： PROBLEM TO BE SOLVED: To provide an image display device capable of preventing occurrence of leakage of a vacuum condition inside a panel in a divided type support body for improving quality and reliability.
SOLUTION: A support body 13 is constructed of a plurality of support body pieces 13X1, 13X2, 13Y1, and 13Y2 and a plurality of corner support body pieces 13C1-13C4 jointing respective end parts of the support body pieces 13X1, 13X2, 13Y1, and 13Y2 mutually. When bonding members are arranged on bonding faces bonding the support body pieces 13X1, 13X2, 13Y1, and 13Y2 to the corner support body pieces 13C1-13C4, hermetic bonding is carried out, while locking pieces 16 are installed in the vicinities of the bonding faces between the support body pieces 13X1, 13X2, 13Y1, and 13Y2 and the corner support body pieces 13C1-13C4. In this way, displacement such as a positional slip is hardly caused on the XY plane of the support body itself.

摘要： PROBLEM TO BE SOLVED: To solve ununiformity in the brightness of a projection image in an image display apparatus for obtaining an enlarged projection image by obliquely projecting image light to a rear projection screen.
SOLUTION: This invention is applied to an image display apparatus for projecting an image generated from an image generation source 1 from the rear of a screen 3 through a projection optical system including a projection lens 2, curved reflection mirror 4, 5 and a reflection mirror 6. The screen 3 includes a Fresnel lens sheet 8 forming a concentrical Fresnel lens on an exit surface, and when the prism surfaces of the Fresnel lens are continued, an aspherical shape is formed. Further, an incident surface prism 30 having a prism surface approximately parallel with the lower end of the Fresnel lens sheet 8 is formed on a prescribed area including a position opposed to the Fresnel center on the light incident surface of the Fresnel lens sheet 8. Consequently the brightness of an image displayed on the screen can be uniformed and also the thickness of the image display apparatus can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide a technique suitably suppressing decrease in luminance of a picture while preventing decrease in contrast of the image due to external light from the outside of a screen (image viewing side). SOLUTION: The image display surface (screen) of a projection type display device is provided with an entire surface protective sheet (3) including an optical filter member absorbing a specific wavelength in a peak wavelength of the external light, particularly three-wavelength fluorescent lamp. As the light source for forming an image, light emitting diodes of three colors are used. At least one of the light emitting diodes emits light having a wavelength different from the peak wavelength absorbed by the front surface protective sheet. Thus, the degradation in contrast of the image due to external light is prevented without decreasing the luminance of the set. COPYRIGHT: (C)2007,JPO&INPIT
