<p>A lamp lighting circuit capable of eliminating luminance unevenness and suppressing the variation in a lamp life at low cost if a plurality of circuits in which lamps are connected in series are connected in parallel and an electronic device with the same are provided. In a lamp circuit (1) in which a circuit (S1) with lamps (L1) and (L2) connected in series, a circuit (S2) with lamps (L3) and (L4) connected in series, and a circuit (S3) with lamps (L5) and (L6) connected in series are connected in parallel, a mid point (A) between the lamps (L1) and (L2), a mid point (B) between the lamps (L3) and (L4), and a mid point (C) between the lamps (L5) and (L6), which are voltage points regarded as the same potential with respect to reference potential, are connected.</p> |
