Abstract
A linear polarizer may be formed a blue dichroic dye compound, having a maximum dichroic ratio Kd≤12 in an entire visible wavelength range, and a red dichroic dye compound, having a maximum dichroic ratio Kd≤16 in the entire visible wavelength range. The linear polarizer has a dichroic ratio Kd≥18 and a thickness of less than or equal to 2 micrometers. The linear polarizer may form an achromatic polarizer.
