Claim:
1. A display apparatus, comprising: a backlight assembly configured to emit light; and a display panel configured to receive the emitted light to display an image, the display panel comprising: a display substrate; an opposite substrate facing the display substrate; a wire grid polarizer disposed on at least one of the display substrate and the opposite substrate to polarize the emitted light; and a reflection reducing layer having a grid shape and being disposed on the wire grid polarizer to reduce an amount of a reflected light, the reflected light being generated in response to external light being reflected by the wire grid polarizer, wherein the wire grid polarizer comprises a plurality of grid polarizing layers spaced apart from each other, each of the plurality of grid polarizing layers extending in a first direction, wherein a ratio of a width of each of the plurality of grid layers to the pitch of the grid layers is in a range of about 1:10 to about 3:10, and wherein the reflection reducing layer comprises a plurality of grid layers spaced apart from each other, each of the plurality of grid layers extending in the first direction, wherein a thickness of the grid layers and a thickness of the grid polarizing layers are obtained using an Equation wherein d1 denotes the thickness of the grid layers, d2 denotes the thickness of the grid polarizing layers, λ denotes a wavelength of the external light, n
