PROBLEM TO BE SOLVED: To provide an electro-optical device that can sufficiently shield light made incident from a lateral or oblique direction. SOLUTION: The electro-optical device includes at least a substrate 10, a first light-shielding film 73 having a predetermined width formed on the substrate, a first interlayer insulating film 41 formed on the first light-shielding film 73, a transistor 30 formed on the first interlayer insulating film 41, a second interlayer insulating film 42 formed on the transistor 30, and a second light-shielding film 70 formed on the second interlayer insulating film 42. The electro-optical device is characterized in that the semiconductor layer 1 of the transistor 30 is disposed so as to be covered by the first light-shielding film 73 from the substrate 10 side, and covered by the second light-shielding film 70 from the side opposite to the substrate 10, the second light-shielding film 70 is formed to be wider than the first light-shielding film 73, a portion of the first interlayer insulating film 41 having the minimum film thickness is present between the end of the first light-shielding film 73 and the end of the second light-shielding film 70 in a plan view.
