Abstract:
A liquid crystal display (100) is provided with a laser light source (5), an LED light source (4), and a radiator (2). The laser light source (5) emits laser light (51). The LED light source (4) emits LED light (41). The radiator (2) holds the laser light source (5), and transmits heat produced by the laser light source (5) and releases said heat in the air. The laser light source (5) is positioned lower than the LED light source (4). The liquid crystal display (100) prevents heat from the LED light source (4), which is not easily affected by heat, from being transferred to the laser light source (5), which is easily affected by heat.
