PROBLEM TO BE SOLVED: To improve an area ratio (an aperture ratio) of a display electrode, and to prevent lowering of thin film transistor (TFT) characteristics caused by incidence of light on the TFT, in an active matrix circuit using the TFT as a switching element. SOLUTION: A light shielding area is reduced by arranging a channel of the TFT under a source wire. Additionally, because the source wire is in this way superposed on the channel of the TFT, light incident on the TFT from the upside is cut off with the source wire and does not reach the TFT, and consequently the lowering of the TFT characteristics caused by external light is prevented.
