A display mounting device for fix on a ceiling is provided to perform receiving/unfolding processes by being attached to a ceiling, and to control an angle according to continuous actions of a motor and a transfer screw, thereby being applicable to both large and small displays. A base(10) is fixed to a ceiling. A display is fixed to a mounting member. An unfolding unit(30) consists of a first driving body mounted on the base, and a first displacement body which does straight motion by the first driving body. A lifting up/down unit(40) comprises as follows. A case is rotatively coupled with the base, and has a second guide rail shorter than a first guide rail. A second driving body is embedded in the case. A second displacement body does straight motion by the second driving body. A turning link connects the second driving body with the mounting member, and has an axial pin moving along with the first guide rail.
