Is displayed on the display screen 5 (full screen display) (see the right figure in FIG. 5). Thereby, it can confirm on the screen with the large visual field of the back at the time of back.

  When the shift lever detects the release condition from the back position (for example, the shift lever is set to the parking position), the position of the display screen 5 slides from the second position to the first position. Thereby, since necessary information can be displayed on the display screen 5 having a required size, the vehicle interior space can be used effectively.

  FIG. 6 shows another example of full screen display. For example, in the in-vehicle navigation device 14 in which the destination is set, the display screen 5 is a simple navigation screen at the first position (a screen that simply indicates a course with an arrow, such as displaying a figure in a direction of turning at an intersection). When displayed (see FIG. 5 (left side)), the in-vehicle navigation device 14 may change the travel route due to traffic congestion or road construction. In this case, the position of the display screen 5 is slid from the first position to the second position, and the current travel route and the new travel route are displayed using the full screen display (see FIG. 6).

  Thus, the occupant can be notified that the travel route has changed, and the occupant can confirm the new travel route. Furthermore, when the change of the travel route is displayed on the full screen display, the change of the travel route may be notified to the occupant by a voice or the like through an in-vehicle speaker (not shown).

  When the trigger condition is detected (for example, after a change in the travel route is displayed on the display screen 5 for a certain period of time), the position of the display screen 5 slides from the second position to the first position. Thereby, since necessary information can be displayed on the display screen 5 having a required size, the vehicle interior space can be used effectively.

  FIG. 7 shows another example of full screen display. For example, when a disc is inserted into the in-vehicle DVD device 15, the position of the display screen 5 can be slid from the first position to the second position, and the DVD image can be displayed on the full screen.

  When the navigation function is also desired to be displayed at the same time, for example, the display screen 5 is made up of two screens to display the navigation screen on the upper screen and the DVD screen on the lower screen (see FIG. 7). The two screens may be left and right, and a navigation screen can be displayed closer to the driver's seat and a DVD screen can be displayed closer to the passenger seat.

  One of the release conditions is that the reproduction of the disc is completed, and the position of the display screen 5 is slid from the second position to the first position. Thereby, since necessary information can be displayed on the display screen 5 having a required size, the vehicle interior space can be used effectively.

  Further, when the mobile terminal 16 such as a smartphone is connected, the position of the display screen 5 is slid from the first position to the second position, and can be displayed on the full screen. At that time, for example, the contents of the telephone directory data in the portable terminal are displayed on the display screen 5 and a call is made to the displayed telephone number. In addition, a music list for playing music stored in the mobile terminal can be displayed on the display screen 5 and music playback can be displayed on the full screen.

  FIG. 8 shows another example of full screen display. In the example of FIG. 8, the entire screen is divided into two vertically. For example, phonebook data is displayed at the top of the screen divided into two, and a DVD image or the like is displayed at the bottom of the screen.

  When displaying on a full screen, the screen can be divided into a plurality of screens. For example, in the case of two screens, various screen combinations such as a combination of a navigation screen and music playback are possible. Various combinations such as a navigation screen, a DVD screen, and display of telephone directory data are possible.

  According to the display device 1 of this embodiment, the display screen 5 can be slid between the first position and the second position. When the display screen 5 is at the first position (partial screen display position), the first image (image displayed on the partial screen) is displayed. When the display screen 5 is at the second position (full screen display position), the second image (full screen is displayed). Image to be displayed). In this way, by varying the degree of exposure of the display screen 5 from the housing 4, a full screen display that uses all of the display screen 5 and a partial screen that uses a part of the display screen 5 are displayed. Display can be made. Therefore, the partial screen display and the full screen display can be used properly according to the situation such as the display contents.

  For example, in a situation where partial screen display is sufficient (such as a right turn arrow display at a traffic store in the navigation device 14), the first image (partial screen display image) with the display screen 5 set to the first position (partial screen display position). Is displayed. As described above, since the display is performed on a part of the display screen 5, even the large display screen 5 can effectively utilize the vehicle interior space. On the other hand, in a situation where full screen display is required (for example, when a back monitor is used), the display screen 5 is set to the second position (full screen display position) and the second image (full screen display image) is displayed. Thus, necessary information can be displayed using the entire display screen 5.

  In the present embodiment, when a predetermined trigger condition (a condition indicating a situation that requires full-screen display) is detected, the display screen 5 is slid to the second position (full-screen display position) and the second image ( Full-screen display image) is displayed. Thus, necessary information can be displayed using the entire display screen 5.

  Further, in the present embodiment, when a predetermined release condition (a condition indicating a situation in which full screen display is not necessary) is detected, the display screen 5 is slid to the first position (partial screen display position) to be the first. An image (partial screen display image) is displayed. As a result, necessary information can be displayed using a part of the display screen 5, and the interior space of the vehicle can be used effectively even with the large display screen 5.
