Cholesteric liquid crystal display device |
| abstract |
A cholesteric liquid crystal display device (40) comprises a stack of three cells (10), each cell comprising a layer of cholesteric liquid crystal material (19) capable of being switched between a plurality of states including a planar state in which it reflects light with wavelengths in a central band (31) corresponding to red, green and blue, respectively, and in overtone bands (32, 33) on both sides of the central band (31). Each adjacent pair of cells 10 in the stack is held together by a layer of adhesive (42, 43). At least one of the layers of adhesive (42, 43) includes a red dye which is absorbent of light with wavelengths in the overtone bands (32) on the side of the central band (31) of lower wavelength. The red dye improves the perceived red colour of light reflected from the red cell (10R) by suppressing the overtone bands. The provision of the red dye in the adhesive provides several advantages in manufacture. |
