1. A transflective liquid crystal display device, comprising:
a pair of substrates composed of an upper substrate and a lower substrate that face each other;
a liquid crystal layer interposed between the pair of substrates;
electrodes, which are provided on the pair of substrates, respectively, that drive the liquid crystal layer;
a reflection layer, which is partially provided on an inner surface of the lower substrate, that reflects light incident from the upper substrate;
color filters provided above the reflection layer, in which coloring layers of different colors are arranged corresponding to sub-pixel regions that constitute a display region; and
an illuminating device provided below the external surface of the lower substrate,
the transflective liquid crystal display device displaying images in a reflective region in which the reflection layer exists and in a transmissive region in which the reflection layer does not exist in every sub-pixel region,
colored region in which the coloring layers of the color filters exist and non-colored regions in which the coloring layers do not exist being provided in the reflective regions,
both the colored regions and the non-colored regions being provided so as to overlap peripheries of the electrodes along a longitudinal direction of sub-pixel regions in plan view, and
the non-colored regions extending along a transverse direction of the sub-pixel regions in a shape of a band.
