Polarization member and display device including the same

A display device, comprising:

• a display panel;
• and
• a polarization member on the display panel, the polarization member including a light absorbing dye that absorbs light having a wavelength of greater than about 380 nm and equal to or less than about 450 nm, wherein
• the light absorbing dye includes at least two benzotriazole derivatives, the at least two benzotriazole derivatives are different from each other, and the at least two benzotriazole derivatives cause the polarization member to have a light transmittance in a wavelength range of greater than about 380 nm and equal to or less than about 400 nm of about 5% or less, and
• one of at least two benzotriazole derivatives has a maximum absorption wavelength in the range of 350 nm to 360 nm, and the other of at least two benzotriazole derivatives has a maximum absorption wavelength in the range of 340 nm to 350 nm and 300 nm to 310 nm.

A display device, comprising:

• a display panel, the display panel including:
• a first electrode;
• an organic layer that is on the first electrode and includes an emission layer;
• a second electrode on the organic layer;
• a capping layer on the second electrode;
• and
• an encapsulation layer on the capping layer, and
• a polarization member on the display panel, the polarization member including:
• a polarizer;
• and
• a plurality of functional layers on at least one surface of the polarizer,
• wherein at least one of the plurality of functional layers or the capping layer includes a light absorbing dye that absorbs light having a wavelength of greater than about 380 nm and equal to or less than about 450 nm, and
• wherein the light absorbing dye includes at least two benzotriazole derivatives, the at least two benzotriazole derivatives are different from each other, and the least two benzotriazole derivatives cause the light-absorbing dye to have a light transmittance in a wavelength range of greater than about 380 nm and equal to or less than about 400 nm of about 5% or less, and
• one of at least two benzotriazole derivatives has a maximum absorption wavelength in the range of 350 nm to 360 nm, and the other of at least two benzotriazole derivatives has a maximum absorption wavelength in the range of 340 nm to 350 nm and 300 nm to 310 nm.
