Abstract
A liquid crystal display device has a liquid crystal panel including a liquid crystal cell and a polarizing plate; and a backlight unit including a light source. An outermost surface of the liquid crystal panel on the backlight unit side is a surface of a protective film included in the polarizing plate, an outermost surface of the backlight unit on the liquid crystal panel side is a surface of a diffusion member, and where an arithmetic mean roughness measured on an outermost surface of the liquid crystal panel on the backlight unit side is Ra1, a pencil hardness is P1, an arithmetic mean roughness measured on an outermost surface of the backlight unit on the liquid crystal panel side is Ra2, and a pencil hardness is P2, Expression 1: 33 nm<Ra1<135 nm, Expression 2: Ra2<15 nm, and Expression 3: P1<P2 are satisfied.
