<p>Provided is a planar lighting device capable of achieving various light-emitting patterns by using a comparatively simple configuration. The lighting device (100) has an electrical path formed between a terminal (13_1A) and a power supply circuit (40), and also between a terminal (13_1B) and a power supply circuit (40). An electrical path is also formed between a terminal (13_2A) and a power supply circuit (40), and between a terminal (13_2B) and a power supply circuit (40). The power supply circuit (40) is configured: so as to be capable of adjusting, according to a request, the size of the current flowing to a light-emitting layer (12_1) through the terminal (13_1A), and/or the size of the current flowing to the light-emitting layer (12_1) through the terminal (13_1B); and so as to be capable of adjusting, according to a request, the size of the current flowing to a light-emitting layer (12_2) through the terminal (13_2A), and/or the size of the current flowing to a light-emitting layer (12_2) through the terminal (13_2B).</p> |
