PROBLEM TO BE SOLVED: To provide a reflection liquid crystal display device which has high- speed response and enables bright display. SOLUTION: This liquid crystal display device consists of a liquid crystal cell which is formed by holding chiral neumatic liquid crystals 30 of positive dielectric anisotropy having a natural helix pitch within a range of 1 to 3 times the liquid crystal display thickness in pixel parts between a pair of transparent electrode substrates 21, 22 and is constituted to allow the selection of either one of two quasi stable states as the relaxation state after the occurrence of Frederics transition by impression of voltage, polarizing plates 41 to 42 which are disposed on both outer side of this liquid crystal cell and a reflection plate 51 which is disposed on the further outer side of the one polarizing plate 41. In such a case, the thickness of the liquid crystal layer in the non-pixel parts inclusive of the parts between the pixels is set smaller than the thickness of the liquid crystal display layer in the pixel parts, by which the helix angle of the liquid crystal molecules in an initial state (at the time of no impression of voltage) is varied between the pixel parts and the non-pixel parts. |
