摘要： A backlight unit includes a light guide plate that includes a side surface that is an incidence surface that is normal to a first direction, a light source adjacent to the incidence surface, and a light conversion layer disposed on an upper surface of the light guide plate that changes a wavelength of light incident thereto. The light conversion layer includes a first portion and a second portion arranged in the first direction. The first portion is closer to the incidence surface in the first direction than the second portion, and the first portion is thinner than the second portion.

摘要： A display device includes: a display substrate; an opposing substrate opposing the display substrate; and a light amount control layer disposed between the display substrate and the opposing substrate. The display substrate includes: a first substrate; a thin film transistor o disposed n the first substrate; and a pixel electrode connected to the thin film transistor. The opposing substrate includes: a second substrate; a color conversion layer disposed on the second substrate; and a first polarizer disposed on the color conversion layer. The first polarizer includes: a base substrate; and a linear polarizer disposed on one surface of the base substrate. The first polarizer opposes the pixel electrode. The one surface of the base substrate on which the linear polarizer is disposed has a flatness of about 60 nm or less.
