Abstract
An active matrix substrate includes an insulating substrate in which light-transmitting areas and a light-shielding area are formed. The active matrix substrate further includes: a light-shielding film formed in the light-shielding area on the insulating substrate, with a transparent base material containing carbon particles, the light shielding film being colored with the carbon particles; an inorganic film formed on the light-shielding film; light-transmitting films formed in the light-transmitting areas on the insulating substrate, with a transparent base material containing transparent oxidized carbon particles; gate lines provided on the inorganic film; a gate insulating film provided on the gate lines; thin film transistors provided in matrix on the gate insulating film; and data lines provided on the light-shielding film to intersect with the gate lines. The data lines are electrically connected with the thin film transistors.
