Abstract
A liquid crystal display device includes a first liquid crystal display panel including a first light-transmitting substrate (thickness T2≤0.3 mm), a substrate, a first liquid crystal, a first polarizing plate having a second main surface that is adhered to the first light-transmitting substrate; an adhering layer provided on a first main surface of the first polarizing plate; and a second light-transmitting substrate (thickness T3≤0.3 mm) adhered to the first main surface by the adhering layer (thickness T1≤0.15 mm). An adhesion parameter α is 1.04 or less when a maximum height of an unevenness of the first main surface 0.0005 mm or less, and the adhesion parameter α is 0.43 or less when the maximum height of the unevenness of the first main surface is greater than 0.0005 mm and 0.001 mm or less.
