A reflective film 51 is arranged on the inner surface side (rear surface side) of the light guide portion 5. A vacuum heat insulating panel 14 is arranged on the inner surface side (back surface side) of the reflective film 51.

For example, the dimensions of the light guide unit 50 and the reflective film 51 in the Z direction and the Y direction are substantially the same or the same as the dimensions of the liquid crystal display unit 10 in the Z direction and the Y direction. For example, the light introduction end 52 on the upper side of the light guide 50 faces the LED 31L of the light irradiation unit 31. The dimensions of the vacuum heat insulating panel 14 in the Z direction and the Y direction are slightly smaller or the same as the dimensions of the light guide portion 50 and the reflective film 51 in the Z direction and the Y direction. Such a structure is the same for the door 7.

The light irradiation unit 31 that irradiates the liquid crystal display units 10 and 11 with light is provided at a position different from the position of the vacuum heat insulating panel 14. As a result, the light irradiation unit 31 can supply the illumination light to the liquid crystal display units 10 and 11 even if the vacuum heat insulating panel 14 is provided. The light irradiation unit 31 can be used as a so-called edge light that illuminates the liquid crystal display units 10 and 11.

In the door 6, when each LED 31L of the light irradiation unit 31 generates light along the Z1 direction, the light guide unit 50 transmits the light from each LED 31L through the circuit board 12 having light transmission to the liquid crystal display unit. It leads to the inner surface side of 10 and illuminates the liquid crystal display unit 10 from the inner surface side. At this time, the light from each LED 31L is reflected toward the liquid crystal display unit 10 by the reflective film 51. As a result, the liquid crystal display unit 10 can evenly receive the light from each LED 31L of the light irradiation unit 31 as an edge light from the inner surface side, so that the liquid crystal display unit 10 can evenly display the entire surface. This also applies to the door 7.

In the refrigerator 1 of the first embodiment of the present invention, the liquid crystal display units 10 and 11 are preferably provided over almost the entire area or the entire area of the front surface of the doors 6 and 7, for example. The heat generated by the liquid crystal displays 10 and 11 and their circuit boards is conducted rearward, but this heat can be blocked (stopped) by the vacuum heat insulating panel 14. Therefore, the heat generated by the liquid crystal displays 10 and 11 and their circuit boards 12 and 13 and conducted rearward and the heat cut off (stopped) by the vacuum heat insulating panel 14 are accumulated in the vacuum heat insulating panel 14. The heat accumulated in the vacuum heat insulating panel 14 is transferred to the lower side of the doors 6 and 7 and the left and right fixing members 22, 23, 24, and is released from the heat dissipation holes 25 of the fixing members 22, 23, 24. It can be discharged to the outside of the doors 6 and 7.
