Abstract
A liquid crystal display device includes, in order from an observation surface side to a hack surface side, a thin film transistor substrate including a color filter layer, a pair of electrodes, and a metal wiring line, a liquid crystal layer containing liquid crystal molecules that are horizontally aligned to the thin film transistor substrate and in which alignment of the liquid crystal molecules is changed due to an electric field generated by applying a voltage to the pair of electrodes, a counter substrate, and a backlight, in which the counter substrate includes a reflective layer disposed outside the pixel area and reflecting incident light from the backlight to the back surface side, the pair of electrodes are a first electrode having a planar shape and a second electrode provided with a and the color filter layer is disposed on the observation surface side of the second electrode.
