    摘要： A reflecting plate (9) is disposed in such a manner as to surround a fluorescent tube (1) in a U shape in its axial direction. A light diffusion-transmission plate (8) is disposed in such a manner as to bridge over the open end portions of the U-shaped reflecting plate (9) and to extend in the axial direction of the fluorescent tube (1). A liquid crystal display element (7) is disposed on this light diffusion-transmission plate (8). In the liquid crystal display device having the construction described above, the present invention disposes shading means (6A) for increasing the quantity of light near the filament (4) portions and limiting the quantity of light on the light emission surface (5) inside the fluorescent tube (1).

    摘要： A color cathode ray tube includes an evacuated envelope having a panel portion (1), a neck portion (2), and a funnel portion (3) for connecting the panel portion and the neck portion, a generally rectangular shadow mask (5) having a curved apertured portion (14) having a multiplicity of electron-transmissive apertures, a curved imperforate portion (15) surrounding and integral with the apertured portion and a peripheral skirt portion (16), a generally rectangular support frame (6) for suspending the shadow mask by spot welding the peripheral skirt portion thereto, within said panel portion, a phosphor screen (4) formed on an inner surface of the panel portion, an electron gun (9) housed in the neck portion, and a deflection yoke (8). The shadow mask is provided with a descending step portion (20) extending along an outer edge of the imperforate portion, the peripheral skirt portion is formed by being bent back from an outer edge of the descending step portion, and the peripheral skirt portion is provided with a plurality of beads (17,18) extending in a direction of a height of the peripheral skirt portion and protruding inward in each side of the peripheral skirt portion.
