Abstract

The invention provides a polarization selective color filter and display device including the same. A polarization selection color filter includes: a first color conversion layer including a plurality of first quantum rods absorbing light of a first wavelength and emitting light of a second wavelength that is longer than the first wavelength; and a second color conversion layer including a plurality of second quantum rods disposed on the first color conversion layer, absorbing the light of the second wavelength and emitting light of a third wavelength that is longer than the second wavelength. The polarization selection color filter is applicable to a color filter array of a display device and may improve a contrast ratio.

Description

technical field [0001] One or more exemplary embodiments relate to a polarization selective color filter and a display device having the polarization selective color filter. Background technique [0002] Liquid crystal display (LCD) devices are one of the most widely used flat panel display devices. A typical LCD device includes two display panels including electric field generating electrodes such as pixel electrodes and a common electrode and a liquid crystal (LC) layer disposed between the two display panels. An image is displayed by generating an electric field in the LC layer by applying a voltage to the electric field generating electrodes, determining alignment of LC molecules of the LC layer, and controlling polarization of incident light. [0003] LCD devices utilize color filters to form specific colors. When the light emitted from the backlight light source respectively passes through the red color filter, the green color filter and the blue color filter, the am...
