Abstract
A polarizer includes: an adhesive layer including a binder resin and a light absorbing component dispersed in the binder resin, the light absorbing component including: a first light absorbing component to absorb a first light having a peak wavelength of about 430 nm or less; and a second light absorbing component to absorb a second light having a peak wavelength ranging from about 640 nm to about 720 nm; a phase retardation layer on the adhesive layer; and a linear polarizer on the phase retardation layer.
