Abstract
A polarizer includes a base and a plurality of grids arranged on a surface of the base parallel to one another. Each of the grids comprises an intermediate layer and a semi-transmissive metal layer that reflects a part of external light incident thereon and transmits a part of the external light incident thereon. The semi-transmissive metal layer and the intermediate layer are alternately deposited to include at least two semi-transmissive metal layers. The thicknesses of the semi-transmissive metal layers increases in a direction in which the semi-transmissive metal layer is disposed away from the external light. An organic light emitting display apparatus includes the polarizer and has improved contrast and brightness.
