A liquid crystal display device for displaying multiple colors wherein a light modulation portion (3; 13; 23) containing a liquid crystal or a mixture of liquid crystals is sandwiched between a pair of transparent substrates (2a, 2b; 12a, 12b; 22a, 22b) each having electrodes (1a, 1b; 11a, 11b; 21a, 21b) in a striped pattern on an inner surface of each transparent substrate (2a, 2b; 12a, 12b; 22a, 22b), the electrodes (1b; 11b; 21b) on one transparent substrate (2b; 12b; 22b) perpendicularly intersecting those (1a; 11a; 21a) on the other transparent substrate (2a; 12a; 22a), characterized in that: the light modulation portion (3; 13; 23) includes a plurality of mutually adjacent regions (3a, 3b, 3c; 13a, 13b, 13c; 23a, 23b, 23c) of at least two different kinds which form a single light modulation layer (3; 13; 23) parallel to the transparent substrates (2a, 2b; 12a, 12b; 22a, 22b), each of said regions (3a, 3b, 3c; 13a, 13b, 13c; 23a, 23b, 23c) contains dichroic pigment in addition to the liquid crystal or the mixture of liquid crystals, the dichroic pigment contained in the regions (3a; 13a; 23a) of one kind is different from the dichroic pigment contained in the regions (3b, 3c; 13b, 13c; 23b, 23c) of the other kinds.
Claim 2
Dependent Claim
21 words
The liquid crystal display device according to Claim 1, further comprising a reflection plate (20; 30; 40) to reflect incident light.
Claim 3
Dependent Claim
46 words
The liquid crystal display device according to Claim 1, wherein each of said adjacent regions (3a, 3b, 3c; 13a, 13b, 13c; 23a, 23b, 23c) in the light modulation portion (3; 13; 23) contains a polymer resin supporting the liquid crystal or the mixture of liquid crystals.
Claim 4
Dependent Claim
95 words
The liquid crystal display device according to Claim 1, wherein a shutter layer (15; 28) containing a liquid crystal or a mixture of liquid crystals is laminated on said single light modulation layer in the light modulation portion (13; 23), and the liquid crystal or the mixture of liquid crystals contained in the shutter layer (15; 28) is caused to be orientated in a specific direction with a threshold voltage which is different from a threshold voltage for the liquid crystal or the mixture of liquid crystals contained in the light modulation layer (13; 23).
Claim 5
Dependent Claim
20 words
The liquid crystal display device according to Claim 4, further comprising a reflection plate (30; 40) to reflect incident light.
Claim 6
Dependent Claim
38 words
The liquid crystal display device according to Claim 4, wherein a shield layer (16) is formed in the shutter layer (15) at sites corresponding to boundaries of said regions (13a, 13b, 13c) in the light modulation layer (13).
Claim 7
Dependent Claim
56 words
The liquid crystal display device according to Claim 4, wherein the the shutter layer (28) is constituted from a liquid crystal layer (25) and a pair of orientation layers (26) sandwiching the liquid crystal layer (25), and a polarization plate (27a, 27b) is provided on an outer surface of each of the transparent substrates (22a, 22b).
Claim 8
Dependent Claim
19 words
The liquid crystal display device according to Claim 7, further comprising a reflection plate (40) to reflect incident light.
Claim 9
Dependent Claim
