A backlight for a display device and a display device including the backlight are disclosed. The backlight includes a light guide plate; a light emitting diode substrate; a frame member; and a plurality of adhesive materials spaced apart from each other. The light emitting diode substrate includes a substrate; and a plurality of light emitting diodes fixed to the substrate. The plurality of light emitting diodes are oriented to face a side surface of the light guide plate. A frame member is disposed facing a surface of the substrate that is opposite the plurality of light emitting diodes. In a side sectional view, the plurality of adhesive materials is spaced apart from each other along a length direction of the frame member. The length direction corresponds to a major dimension of the frame member.

A liquid crystal display device includes: a first polarizing plate, a first liquid crystal cell, a second polarizing plate, a third polarizing plate, a second liquid crystal cell, and a fourth polarizing plate, which are arranged from a front side to a back side in this order. P1, P2, P3, P4 represent degrees of polarization of the first polarizing plate, the second polarizing plate, the third polarizing plate, and the fourth polarizing plate, respectively, one of a relational expression of P1&#x3e;P2, P3, P4, a relational expressions of P4&#x3e;P1, P2, P3, and a relational expression of P1, P4&#x3e;P2, P3 is satisfied.
