A method for manufacturing an eye-protecting liquid crystal display device is disclosed, in which an ultraviolet light emitting material and a ultraviolet absorbent are added in a first planarization layer of an array substrate and a second planarization layer of a color filter substrate. The ultraviolet absorbent absorbs short-wavelength blue light having a wavelength less than 400 nm and ultraviolet light emitting from a backlight module. The short-wavelength blue light and the ultraviolet light so absorbed excite the ultraviolet light emitting material to give off long-wavelength visible blue light having a wavelength greater than 400 nm. The first and second planarization layers are thus useful in converting ultraviolet light and short-wavelength blue light having a wavelength less than 400 nm, which could damage human eyes, into long-wavelength visible blue light having a wavelength greater than 400 nm that does not damage human eyes.
