A liquid crystal display device includes: a liquid crystal display panel having a pair of substrates which is arranged to face each other in an opposed manner with liquid crystal sandwiched therebetween; and a backlight arranged on a one-side surface of the liquid crystal display panel. Thin film transistors are formed on a liquid-crystal-side surface of the substrate on a backlight side. In such a liquid crystal display device, the thin film transistor is constituted of a gate electrode, a gate insulation film which is formed so as to cover the gate electrode, a semiconductor layer which is formed on an upper surface of the gate insulation film, and a pair of electrodes which is arranged to face each other in an opposed manner on an upper surface of the semiconductor layer from the substrate side as viewed in a plan view. The semiconductor layer is formed of a stacked body consisting of a microcrystalline semiconductor layer and an amorphous semiconductor layer from the substrate side, and the semiconductor layer is formed in an island shape within a region where the gate electrode is formed as viewed in a plan view. Each one of the pair of electrodes is formed such that, as viewed in a plan view, sides of the each one electrode excluding a side of the each one electrode which faces the other electrode project outwardly from the semiconductor layer, and a portion of the each one electrode which projects outwardly from the semiconductor layer overlaps with the gate electrode at least on the periphery of the semiconductor layer.
