Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an inexpensive substrate capable of simply adjusting capacitances serially connected to respective discharge tubes, and restraining manufacturing cost; a discharge tube current equalization lighting device using the substrate; and a liquid crystal display. SOLUTION: This substrate is provided with: a plurality of first conductors 301 and 302 formed on a surface S of an insulating substrate 16a by being separated from one another, and connected to the respective discharge tubes; capacitance-adjusting second conductors 311 formed between the first conductors 301 and 302 adjacent to each other on the surface S in a state without being connected to any of the first conductors; and a third conductor 32 formed oppositely to the first conductors 301 and 302 and the second conductors 311 on the back surface R of the insulating substrate 16a. As a result, capacitances can be formed in regions where the first conductors 301 and 302 overlap the third conductor 32. The values of the capacitances can be varied depending on whether the capacitance-adjusting second conductor 311 is jointed to either of the first conductors 301 and 302 adjacent to each other or not. Accordingly, the capacitances connected in series to the respective discharge tubes can be adjusted on a discharge tube basis, and high-frequency currents having values nearly equal to one another can be supplied to the respective discharge tubes.
