Abstract

A display device includes: a display substrate (110); an opposing substrate (210) opposing the display substrate (110); and a light amount control layer (310) disposed between the display substrate (110) and the opposing substrate (210). The display substrate (110) includes: a first substrate (111); a thin film transistor (TFT) disposed on the first substrate (111); and a pixel electrode (PE) connected to the thin film transistor (TFT). The opposing substrate (210) includes: a second substrate (211); a colour conversion layer (230) disposed on the second substrate (2111); and a first polariser (510) disposed on the color conversion layer (230). The first polariser (510) includes: a base substrate (511); and a linear polariser (512) disposed on one surface of the base substrate (511). The first polariser (510) opposes the pixel electrode (PE). The one surface of the base substrate on which the linear polariser is disposed has a flatness of about 60 nm or less. The first polariser (510) can be a wire grid polariser or an absorbing polariser. The first polariser (510) is manufactured by forming a base substrate (511) on a carrier substrate (550), forming a linear polariser (512) on the base substrate (511), and removing the carrier substrate (550). The colour conversion layer (230) can comprise red and green conversion portions and a transmissive portion.
