The source board 621 may also include a flexible film-type cable structure, and extends upward along the side of the transparent display assembly 60 to form the T-CON at the top of the sub door 50. ) may be connected to the board 623.

In detail, when the source board 621 is placed behind the display 62, there is a possibility that it will be exposed to the outside through the transparent portion 21 due to the transparent nature of the display 62. Accordingly, the source board 621 may be formed at a peripheral end of the display 62 and may be bent to contact the outer surface of the module frame 67 outside the module frame 67 . The source board 621 may be formed in an FFC or FPC structure that is easy to bend. Accordingly, the source board 621 can be arranged along the module frame 67. Additionally, the source board 621 may be formed to a corresponding size so as not to deviate from the area of the module frame 67 while being in close contact with the module frame 67 .

Of course, the source board 621 may be formed at the top or bottom of the display 62, but due to the nature of the structure of the display 62 in which the top and bottom lengths are longer than the left and right widths, the source board 621 is formed at both left and right ends of the display 62. When placed at one end of either side, sufficient space for the source board 621 to be formed can be provided.

Meanwhile, both ends of the display 62 may be supported by interstitial bars 63. The interstitial bar 63 may be formed in a rod shape extending from the top to the bottom of the display 62, and may be composed of a first interpolation 631 and a second interpolation 632.

The light guide plate 64 is located at the rear of the display, and can be spaced a predetermined distance away from the display 62 by the first and second bars 631 and 632. Depending on the position of the light guide plate 64, there may be a difference in the depth of the screen output from the display 62.

Therefore, the light guide plate 64 is positioned further forward than the midpoint between the front panel 61 and the rear panel 65 so that the screen output from the display 62 feels closer to the front panel 61. It can be configured, and the heights of the first gap 631 and the second gap 632 can be determined accordingly.

The protruding portion of the rear panel protrusion 651 may be seated on the door liner 56 when the transparent display assembly 60 is mounted, and an insulating material 531 will be formed inside the sub door 50. This forms a space where the foaming liquid can be filled.

The rear panel 65 may be made of low-ε glass for insulation. Low-E glass is a type of glass with excellent thermal insulation effects that is formed by forming a low-emissivity coating layer on the surface of the glass for thermal insulation. Accordingly, the rear panel 65 can prevent cold air inside the refrigerator from being transferred to the outside through the transparent display assembly 60.

A spacer 66 may be provided between the rear panel 65 and the light guide plate 64. The spacer 66 may be formed in the shape of a rectangular frame formed along the circumference of the light guide plate 64, and is attached to the light guide plate 64 and the rear panel 65 to connect the light guide plate 64 and the rear. The panels 65 can be maintained at regular intervals.

The gap between the front panel 61 and the light guide plate 64 is maintained at a fixed distance for screen output on the display 62. Additionally, the distance between the light guide plate 64 and the rear panel 65 may be determined according to the thickness of the sub door 50 or the overall thickness of the transparent display assembly 60. That is, by adjusting the thickness of the spacer 66, the overall thickness of the transparent display assembly 60 can be determined and mounted according to the specifications of the sub door 50.

Meanwhile, the rear panel 65 is in contact with the door light 57, and the distance between the display 62 and the door light 57 can be determined depending on the position of the rear panel 65. The door light 57 may function as an auxiliary backlight of the commercial display 62 when turned on.

In detail, the distance between the display 62 and the door light 57 may be between 5 cm and 15 cm. If the distance between the display 62 and the door light 57 is less than 5 cm, there is a problem of internal contrast, and if it exceeds 15 cm, the backlight function may not be performed. Therefore, in order to maintain the distance between the display 62 and the door light 57, the rear panel 65 is also maintained at a predetermined distance from the display 62, and the width of the spacer 66 is determined. You can.

The spacer 66 can make the space between the light guide plate 64 and the rear panel 65 airtight. Therefore, the space between the spacer 66 and the light guide plate 64 may be made into a vacuum state or an insulating gas such as argon may be injected to further improve the insulating performance.

While the rear panel 65 is attached to the spacer 66, the outer end of the rear panel 65 may extend further outward than the spacer 66. In addition, the module frame 67 is mounted on the outer end of the rear panel 65, so that the rear panel 65 and the front panel 61 can be fixed to each other.

The module frame 67 may connect the back of the front panel 61 and the front of the rear panel 65 and form a peripheral surface of the transparent display assembly 60. Additionally, a space where the display light 68 can be mounted can be provided on the inner surface of the module frame 67.

The module frame 67 may be formed in a rectangular frame shape, and is sized to accommodate the light guide plate 64 and the spacer 63 therein. In addition, display lights 68 may be mounted on the top and bottom of the module frame 67, respectively, and the light guide plate 64 may be used to control the display lights 68 disposed at the top and bottom of the module frame 67. It can be located in between.

Therefore, the light irradiated through the display light 68 can be directed to the end of the light guide plate 64 and can move along the light guide plate 64 to cause the light guide plate 64 to emit light from the entire surface. .

Sealant 691 may be applied around the module frame 67. The sealant 691 may be applied to form a peripheral surface of the transparent display assembly 60 and forms a peripheral surface between the front panel 61 and the rear panel 65.

The sealant 691 seals the transparent display assembly 60 to prevent air from entering the interior, and may be made of polysulfide (also called thiokol) material. Of course, if necessary, it may also be made of other sealant materials such as silicone or urethane that can directly contact the foaming liquid injected to form the insulating material 531.

The sealant 691 allows the module frame 67, the front panel 61, and the rear panel 65 to remain coupled, and at the same time completely seals the connection portion of each component to prevent moisture or moisture from entering. It can be prevented. Additionally, the sealant 691 is a portion that is directly in contact with the foaming liquid during molding of the insulating material 531 and can protect the perimeter of the transparent display assembly 60.

In addition, the sealant 691 allows cables 601, 605, and 606 connected to the touch sensor 612, display panel 62, and display light 68 inside the transparent display assembly 60 to enter and exit. That is, the sealant 691 blocks the outer surface of the cables 601, 605, and 606 when the cables 601, 605, and 606 extend outward through the peripheral surface of the transparent display assembly 60, allowing water to enter and exit the space where the cables 601, 605, and 606 enter. Alternatively, it can block moisture from entering.
