Furthermore, in order to reproduce a sense of reality due to the three-dimensional sound effect, the width dimension of the cabinet including the speakers arranged on the left and right sleeves of the display screen is further increased. An outline of the cabinet of the thin display device including a long horizontal line constituted by a geometric straight line, and a horizontal line constituting a connecting line between a ceiling and a wall surface of the room where the thin display device is installed, a window frame, and the like When the angle formed is deviated from the parallel or right angle, it causes a feeling of instability and potential dissatisfaction for the user of the thin display device.

A thin display device using a thin display panel such as a liquid crystal display panel or a plasma display panel as a display element can be mounted on a wall because it is much lighter and thinner than a conventional display device using a cathode ray tube. In many cases, the horizontal line joining the ceiling and the wall surface or the wall surface and the floor surface, or the outline of furniture or fixtures in the vicinity of the place where the thin display device is installed are visible within the same field of view when viewing the display screen of the thin display device. It is easy to notice the angle deviation.

Despite its large display screen, it has a novel design that is lightweight and thin, and has a space-saving feature when installed. In many cases, depending on the assembly accuracy of the display unit main body and the stand of the thin display device, the frame of the screen display unit of the thin display device and the horizontal horizontal line of the cabinet constituting the outline of the cabinet are installed. The angle deviation from the horizontal line included in the background in the environment is easily recognized as described above.

In order to measure the level of the device with high accuracy, the light emitting element and the two light receiving elements are arranged in parallel so as to sandwich a bubble tube enclosing a liquid and bubbles as shown in Patent Document 1 to measure the level of the apparatus with high accuracy. In addition to the invention, the invention is arranged to detect the difference in the amount of light received by the two light receiving elements through the bubble or liquid in the bubble tube and convert the light from the light emitting element into an electrical signal and convert it into the tilt angle of the surface to be measured. As can be seen in Patent Document 2, a tilt sensing device has been invented that displays on a liquid crystal display which direction it should be rotated to obtain a horizontal or vertical state.
