摘要： An electron beam indicator, for example, for a large-screen display which has a two-dimensional arrangement of a plurality of electron beam indicators. The electron beam indicator tube comprises fluorescent trios each of which have a plurality of fluorescent layers which function as picture elements, and a plurality of linear cathodes which are disposed respectively opposite to the fluorescent layers of the fluorescent trios. A common accelerating electrode is disposed between the fluorescent trios and control electrodes, and a separator structure is disposed so as to shield the fluorescent layers of each fluorescent trio. The common accelerating electrode is curved in the direction which the linear cathodes extend in a convex shape which bulged outwardly toward the fluorescent layers, and is formed so that the width of the electron beam transmission apertures decreases from the central portion toward the opposite ends. The electron beam which impinge on the separators of the separator structure are cut off by the accelerating electrode to which a low voltage is applied and hence the reactive current is reduced and luminous efficiency of the fluorescent layers is improved and the power consumption is reduced.

摘要： The present invention relates to a backlight apparatus and a liquid crystal display apparatus, capable of realizing a backlight apparatus having high color reproductivity without color irregularities in a backlight apparatus having a LED device as its light source. In the optical unit 61, there are disposed the dichroic mirror B which transmits green light Lg and red light Lr and reflects blue light Lb, the dichroic mirror G which transmits the light Lb and the light Lr and reflects the light Lg, and the dichroic mirror R which transmits the light Lb and the light Lg and reflects the light Lr, and they transmit or reflect the light emitted from the LED devices 11B, 11G and 11R to mix to form the white light Lw. The light Lw formed by the dichroic mirrors B, G and R is entered to the light guiding plate 62 by the mirror performing a total reflection. Therefore, in the backlight apparatus having an LED device as its light source, it is possible to realize a backlight apparatus having high color reproductivity, without color irregularities.
