Abstract:
1. A cholesteric liquid crystal display device comprising: a first liquid crystal panel containing a first cholesteric liquid crystal material for reflecting a light of a first color; a second liquid crystal panel containing a second cholesteric liquid crystal material for reflecting a light of a second color; a third liquid crystal panel containing a third cholesteric liquid crystal material for reflecting a light of a third color; a light absorption layer combined to a lower portion of the third liquid crystal panel; a first double-sided adhesive buffer layer positioned between the first liquid crystal panel and the second liquid crystal panel to combine the second liquid crystal panel to a lower portion of the first liquid crystal panel; and a second double-sided adhesive buffer layer positioned between the second liquid crystal panel and the third liquid crystal panel to combine the third liquid crystal panel to a lower portion of the second liquid crystal panel, wherein the first double-sided adhesive buffer layer and the second double-sided adhesive buffer layer comprise a film, a first adhesive layer positioned on a top surface of the film, and a second adhesive layer positioned on a lower surface of the film, and the first adhesive layer and the second adhesive layer have different adhesive strengths.
