摘要: This invention discloses a color liquid crystal display device which can be applied to 7-segment numeric display, for example. A pair of transparent electrodes (12, 13) are disposed on the inner surfaces of a pair of transparent substrates (10, 11) facing each other. One (13) of the transparent electrodes has a function as the display segments and is constituted by two comb tooth-like electrodes (13 G, 13R) that are fixed in a predetermined direction. The direction of teeth of these two comb tooth-like electrodes is in agreement with each other. The other - (12) of the transparent electrodes has a flat sheet-like shape. Color filters (14G, 14R) of two colors are alternately disposed on the two comb tooth-like electrodes (13G, 13R) in such a manner as to face the other (12) of the transparent electrodes. The direction of disposition of the color filters (14) is in agreement with the direction of the teeth of the comb tooth-like electrodes (13G, 13R). The color filters - (14) are disposed on the entire surface of the display range (20) including the display segment (a -g). A liquid crystal (18) is sealed between the color filters - (14) and the other (12) of the transparent electrodes. A voltage is applied across the pair of the transparent electrodes and controls the transmission quantity of the liquid crystal. Thus, segment display can be effected.

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 liquid crystal color display element has striped red, green and blue color filters (R,G,B) and comb electrodes (5R, 5G,5B) corresponding to the respective red, green and blue color filters. At least two of the comb electrodes are connected in parallel and interlieved with an independent electrode composed of the remaining comb electrode.

摘要: A liquid crystal color display apparatus includes a liquid crystal display panel having a section with transparent elctro- des (11, 35) provided with color filters (12, 13, 36) in striped formation and another section with transparent electrodes (11, 34) provided with no color filters, and separate electrode drive circuits (7, 8) for applying a voltage (V1) to the electrodes of the former section and another voltage (V2) to the electrodes of the latter section, with the intention of achieving little difference of brightness between both sections. The color filters (12,13) in striped formation are provided in the entire area including display pattern segments (a, b, c, d, e, f, g) having the arrangement of the transparent electrodes (11, 35) and a background area without transparent electrodes, with the intention of equalizing the visibility of unlighted segments (d, e, f, g) and the background.
