According to an embodiment of the present invention, a guide panel includes: a first guide part in the shape of a frame; a second guide part formed on an outer surface of the first guide part; and a third guide part which is formed on an outer surface of the second guide part and is in the shape of a frame. When a reflective sheet is installed on the guide panel, a portion of the guide panel having a color different from a color of the reflective sheet is exposed. Therefore, whether the reflective sheet and the guide panel are assembled correctly or not can be easily checked with the naked eyes of a user. |
