The present invention relates to a door lighting structure for a showcase refrigerator capable of realizing an LCD image, and more particularly, it is easy to disassemble and assemble to replace the lighting by configuring the lighting structure to irradiate light toward the interior space of the refrigerator. Of course, the present invention relates to a door lighting structure for a showcase refrigerator, which can realize an LCD image, which can reduce costs and effectively prevent condensation that may occur on the door by adjusting the surface temperature of the door by the lighting structure.

In general, a place that handles food, such as homes, restaurants, convenience stores, and beverage stores, etc., install and use various types of refrigerators to store food or drinks at low temperatures so as not to cool or rot. Furthermore, in a place for the purpose of selling goods, such as a convenience store or a store, a transparent window is formed on the door so that the buyer or seller can easily check the goods stored inside, so that the goods stored inside the refrigerator can be checked. Install and use a showcase refrigerator.

These showcase refrigerators provide the buyer with the inside of the refrigerator as it is, providing visual display of the items stored therein, as well as reducing unnecessary opening time of the door, and allowing the seller to arrange or display the items inside the refrigerator. There is a merit that it is easy to do, but on the other hand, if the goods inside are sparsely, there is a problem such that the effect of exhibiting is rather deteriorated if the goods are not filled by the seller's carelessness.

Therefore, recently, the LCD has a structure equipped with a liquid crystal cell that can reproduce and reproduce various images on the front of the showcase refrigerator, that is, the transparent window of the door.
