A liquid crystal display device includes: liquid crystals; a circuit layer which includes a thin-film transistor and wirings, the wirings being formed from metal; a pixel electrode and a common electrode which are stacked on each other between the liquid crystals and the circuit layer with an insulating film disposed therebetween in order to drive the liquid crystals in a transverse electric field driving mode, and each of which is formed from a transparent conductive film; a color filter which includes coloring layers of different colors, the coloring layers having different transmittances; and a connection wiring. The wirings includes a common wiring which is disposed so as not to face the coloring layer having the highest transmittance among the coloring layers but to face any one of the other coloring layers. The connection wiring connects the common electrode and the common wiring to each other.
