Description

  The present invention relates to a display body frame and a display device, and more particularly to a display body frame for housing a display body in which a display panel is housed in a display panel case so that one main surface of the display panel is exposed. The present invention relates to a display device in which a display body is housed in a frame.

  In recent years, a liquid crystal display that displays characters and other images by driving a liquid crystal sealed in a gap between both substrates by selectively applying a voltage to a plurality of electrodes provided on opposing surfaces of a pair of substrates. A liquid crystal display device having a panel is often used as a display means such as a mobile phone or a PDA.

  FIG. 4 is a schematic cross-sectional view showing an example of a liquid crystal display device in which a liquid crystal display is housed in a conventional display frame. In this conventional example, a main liquid crystal display panel and a main liquid crystal display panel are shown. A liquid crystal display device including a liquid crystal display body having two liquid crystal display panels, ie, a sub liquid crystal display panel formed small in a planar shape, will be described.

  As shown in FIG. 4, the main liquid crystal display panel 32 and the sub liquid crystal display panel 33 are arranged so that the non-viewing surfaces face each other. A light guide plate 36 for guiding the irradiation light to the panels 32 and 33 is disposed, and a light source 37 for irradiating the liquid crystal display panels 32 and 33 through the light guide plate 36 is guided in the vicinity of the light guide plate 36. The light plate 36 is disposed to face the side surface.

  According to the liquid crystal display device 31 described above, the flexible wiring board 32b connected to the terminal portion 32a of the main liquid crystal display panel 32 is bent and the other end portion is the display panel case main wall of the display panel case 39. 43, and the portion of the flexible wiring board 32b that is attached to the outer surface of the display panel case main wall 43 is pressed by the display main frame frame wall 47 that is disposed to face the display panel case main wall 43. Yes. For this reason, the main liquid crystal display panel 32 may be lifted from the display panel case 39 due to the repulsive force of the flexible wiring board 32b caused by the bending of the flexible wiring board 32b. As a result, the main liquid crystal display panel 32 falls from the display body frame 42, and further, contacts with other electronic components disposed in the vicinity of the liquid crystal display device 31 and is damaged. Had the problem of fear.

  The present invention has been made in view of these points, and prevents the display panel from being lifted up from the display panel case, thereby causing damage to other components disposed in the vicinity. It is an object of the present invention to provide a display frame and a liquid crystal display device that can prevent such a situation.

  In order to achieve the above object, the display frame according to the present invention is characterized in that the display panel is housed in a display panel case so that one main surface of the display panel is exposed, and the terminal portion of the display panel. One end portion of the connected flexible wiring board is bent after being extended to the outside of the display panel case, and the display panel case is arranged to face the other main surface of the display panel. In a display body frame for storing a display body adhered to the outer surface of the main wall, the display body frame main wall disposed opposite to the display panel case main wall and the side surface of the display body A display-body frame side wall, and a tip end portion of one of the display-body frame side walls extends to a position facing the terminal portion of the display panel. Display In that it constitutes a use holder.

  According to the display body frame according to the present invention, when the display body is housed inside the display body frame, the connection surface between the terminal portion and the flexible wiring board is covered by the display body holding portion. Yes. For this reason, even when a load is applied to the display panel in the direction of lifting from the display panel case due to the repulsive force of the flexible wiring board caused by bending of the flexible wiring board, the display body holding unit displays the display. One end portion of the panel can be pressed, and as a result, the display panel can be prevented from floating and falling from the inside of the display panel case.

  The display panel is housed in the display panel case so that a connection surface between the terminal portion and the flexible wiring board is exposed, and the display body holding portion covers the connection surface. Further, it is preferable to extend from the front end portion of the display body frame side wall.
