A main body tilt detecting unit detects that a tilt of the main body is in a second style state that satisfies a style condition. A dual-screen display control unit, in response to detection that a degree of opening of the main body is in a first style state, and to detection that a tilt of the main body is in a second style state, causes an app image for a first app associated with the style states to appear on a first screen, and causes an app image for a second app associated with the style states to appear on a second screen. A style-based processing execution unit performs processing associated with the style states by use of the apps. ## Claims ### Claim 1 A display device comprising: a main body including a first body being plat-shaped including a first screen provided at a front side of the first body, opposite a back side of the first body, a second body being plate-shaped including a second screen provided at a front side of the second body, opposite a back side of the second body, and a connecting part that connects the first body and the second body to enable rotation of the first body and second body about the connecting part, wherein when the main body is in a fully-closed state, the back side of the first body is in contact with the back side of the second body;
