Abstract
A liquid crystal display device includes: a component substrate including a transistor device; an opposing substrate disposed so as to face the component substrate through a liquid crystal layer; a back light disposed on a side of the component substrate located opposite to the opposing substrate; first and second measurement portions formed on a surface of the component substrate and the opposing substrate, respectively, located on the liquid crystal layer side and used for measuring a difference between bonding positions of the component substrate and the opposing substrate; a measurement opening portion disposed on the second measurement portion side; and a light shielding layer disposed between the component substrate and the second measurement portion and preventing transmission of light from the back light through the measurement opening portion.
