Abstract
A liquid crystal display (“LCD”) device and a method of manufacturing the LCD device, the LCD device including: a substrate including a display area and a non-display area; a blue light blocking filter on the substrate; a plurality of color pattern layers spaced apart from one another in a plan view; a black matrix among the plurality of color pattern layers in a plan view; a planarization layer on the color pattern layer and the black matrix; and a polarizer on the planarization layer. The color pattern layer includes: a red color conversion unit on the blue light blocking filter, the red color conversion unit converting a light into a light having a red wavelength; and a green color conversion unit on the blue light blocking filter, the green color conversion unit converting a light into a light having a green wavelength, and the red color conversion unit and the green color conversion unit include wavelength converting particles.
