The present invention relates to a front door of a building which can perform lighting and ventilation. The present invention has an operation plate installed in the inside of the front door to be able to slide and is formed to be able to simply convert an opaque state, a lighting state, and a wind state due to the movements of the operation plate. The present invention comprises a door (10) which guides horizontal movements of the operation plate (20) by having a plurality of guide frames (17) between an inner side (11) and an outer side (15); the operation plate (20) in which a handle (18) moves along a horizontal slit hole (13); an opaque plate unit (21) which is formed with opaque materials to prevent light from being transmitted through a lower front surface (25) and an upper front surface (27); a transverse plate unit (33) including a reflective film (22-1) inside in order for the light facing the lower end to be reflected towards the lower surface unit (25); and a control device (30). |
