<p><P>PROBLEM TO BE SOLVED: To provide a light source drive circuit, a light source device, and a display device capable of reducing an increase in an output voltage with small power consumption even if a problem such as a broken line or the like occurs. <P>SOLUTION: A light source element 20 has one end connected to an output terminal 13 and the other end connected to one end of a resistive element 15. The resistive element 15 has one end connected to the other end of the light source element 20, and the other end connected to the ground. A Zener diode 16 has a cathode connected to an output terminal 13 and an anode connected to a feedback voltage applying terminal 14. The resistive element 17 has one end connected to the feedback voltage applying terminal 14 and the other end connected to a node between the light source 20 and the resistive element 15. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
