    摘要: A display device comprises a display element for displaying luminous images corresponding to color information on a second face of a screen; a polarization converting sheet which is disposed on the screen so that light irradiated from the screen enters and transmits selectively light having a first mode of polarization; and a liquid crystal color shutter which is disposed on the polarization converting sheet and transmits selectively light having the first mode of polarization so as to output as light of at least one color of primary colors corresponding to the color information. A display device may be an achromatic CRT. Thereby, a display device bright and large in its display screen can be realized with a simple constitution.

    摘要: A fluorescent lamp characterized in that the charging tendency of a phosphor used is positioned more negative side than that of metal oxides each having a metal ion electronegativity X.sub.i of 7.0 but more positive side than that of metal oxides each having a metal ion electronegativity X.sub.i of 11.8, that particles of the phosphor are charged positive and smaller than 3.0 .mu.C per gram when they are in contact with soda lime glass beads each having a particle size of 200-500 .mu.m, or that they are charged negative and larger than -0.5 .mu.C per gram when they are in contact with reduced iron powder having a particle size of 44-74 .mu.m.
