摘要：
A sheet heater includes a substrate; a first and second finger electrode each on the substrate to lengthwise extend in a first direction and be spaced apart from each other in a second direction; and a heating layer on the substrate to have a stripe shape lengthwise extended in the second direction to cross each of the first and second finger electrodes. The first finger electrode or the second finger electrode crossed by the heating layer is a pattern electrode in which an opening is defined, for the pattern electrode in which the opening is defined, an opening ratio is defined by a total planar area of the opening to a total planar area of the pattern electrode, and the opening ratio is in a range from about 40% to about 80%.
