Abstract

A curtain device according to an embodiment of the present invention includes a first shade bar. A first shade roller is disposed within the first shade bar and a hook portion is provided in an upper side of the first shade bar. A first curtain member has a first transmissivity. One end of the first curtain member is rolled into the first shade roller and an opposite end of the first curtain member is exposed to a bottom of the first shade bar. A second shade bar is adjacent the bottom of the first shade bar. A second shade roller is configured to be disposed inside a door body that is formed in a lower portion of the door frame. A second curtain member having a second transmissivity has one end connected to the second shade bar and an opposite end rolled into the second shade roller.
