Abstract:
The liquid crystal panel has a front-surface plate, a front-side polarizing plate, a liquid crystal display element, and a rear-side polarizing plate in an integrally laminated state, in which the front-surface plate and the front-side polarizing plate are in the state of being laminated with each other via an adhesive layer having a thickness of 2 μm or more, and the liquid crystal panel satisfies Formula A-1: 2020 μmGPa>ECp×dCp×εCp×(100−P)/100+(Ef×df×εf)−(Er×dr×εr)>0 μmGPa (ECp is the modulus of elasticity, dCp is the thickness, and εCp is the humidity dimensional change rate, of the front-surface plate, Ef is the modulus of elasticity, df is the thickness, and εf is the humidity dimensional change rate, of the front-side polarizing plate, Er is the modulus of elasticity, dr is the thickness, and εr is the humidity dimensional change rate, of the rear-side polarizing plate, P is the stress relaxation rate of the adhesive layer).
