摘要:
A liquid crystal panel has a first optical film (4) adhered to a viewing side of a liquid crystal cell (2) through a first pressure-sensitive adhesive layer (3), and a second optical film (6) adhered to the reverse side of the liquid crystal cell (2) through a second pressure-sensitive adhesive layer (5). A creep value (L1) of the first pressure-sensitive adhesive layer (3) is from 50 to 3000 μm. A creep value (L2) of the second pressure-sensitive adhesive layer (5) is from 10 to 400 μm. The creep value (L1) of the first pressure-sensitive adhesive layer (3) is larger than the creep value (L2) of the second pressure-sensitive adhesive layer (5). The creep value means the shift amount after one hour of the pressure-sensitive adhesive layer having a thickness of 20 μm in a case where a tensile shearing force of 4.9 N is applied to an adhesive area of 10 mm2 at 23° C.
