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, wherein a 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, and a 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.
