1. A liquid crystal display device, comprising:
- a liquid crystal display element in which a pair of transparent substrates, each having at least a display electrode and an orientation film positioned such that the display electrodes are opposed to each other, are arranged, and a liquid crystal layer is interposed between the transparent substrates such that a plurality of pixel regions are formed; and
a backlight arranged outside thereof so as to irradiate a display region of the liquid crystal display element, whereina reflectable metal film having a light transmission hole is formed on an inner surface or inner surfaces of one and/or the other of the transparent substrates,a light transmission region for transmitting light from the backlight through the light transmission hole and a light reflection region for reflecting outside light other than the light from the backlight on the metal film are arranged within the single pixel region,a first color filter and a second color filter of similar colors that differ in tone are formed in each of the pixel regions on the inner surface or inner surfaces of the one and/or the other of the transparent substrates, anda boundary between the first color filter and the second color filter in each of the pixel regions is positioned in the light reflection region of the pixel region.

Abstract
A reflectable metal film having a light transmission hole 5 is formed on an inner surface of a transparent substrate 2, and a light transmission region 7 and a light reflection region 8 are arranged within each of pixel regions on the inner surface of the transparent substrate 2. A first color filter 9 and a second color filter 10 of a similar color that differs in tone are formed in each of the pixel regions. A boundary 11 between the first color filter 9 and the second color filter 10 in each of the pixel regions is positioned in the light reflection region 8 in the pixel region.
