摘要

PROBLEM TO BE SOLVED: To reduce the number of light sources, and to illuminate excellently a transmission light-emitting part of an indicator panel and an indicator light- emitting part. SOLUTION: A light guide plate 31 is arranged close to the back of an indicator panel 3. A liquid crystal display device (LCD panel) 6 is arranged on the front of the indicator panel 3. A light source for an LCD 11 for illuminating the LCD panel 6 in the daytime and a light source for the indicator panel 9 for illuminating a transmission light-emitting part of the indicator panel 3 in the night-time are arranged on the back side of the LCD panel 6. A light source for an indicator 50 for illuminating an indicator light-emitting part 47 of the indicator panel 3 is arranged on the rear side of the light guide plate 31 corresponding to the indicator light-emitting part 47. A reflecting film 69 is installed on the back of the indicator panel 3, and a hole for guiding light of the light source for an indicator 50 to the indicator light-emitting part 47 is formed on a spot corresponding to the indicator light-emitting part 47 of the film 69.
