  The display unit of the electronic device includes a so-called “design panel” whose surface portion is exposed to the outside of the electronic device when the electronic device is assembled. On the surface portion of the design panel, a surface that is decorated to improve the aesthetics of the electronic device, that is, a so-called “design surface” is formed. A conventional electronic device has a structure in which a liquid crystal module, a holder, an electronic circuit board, and the like are fixed to a back surface portion of a design panel, and a display surface of the liquid crystal module is exposed to the outside of the electronic device through a hole that penetrates the design panel. there were.

  In the conventional electronic device, the display unit is assembled as follows. First, the cover panel is bonded to the hole of the design panel from the front side or the back side of the design panel. Next, the design panel is placed on a jig or the like. At this time, the surface portion of the design panel is arranged vertically downward, and the design surface is held in contact with a jig or the like. While the design surface is in contact with a jig or the like, the liquid crystal module, the holder, the electronic circuit board, and the like are fixed with screws from the back side of the design panel.

  In conventional electronic devices, the design panel is placed on a jig or the like at the initial stage of assembly, and the liquid crystal module, holder, electronic circuit board, and the like are sequentially fixed while the design surface of the design panel is in contact with the jig or the like. Therefore, there was a problem that the design surface was easily damaged during the fixing work. In particular, a product using a large design panel has a large design surface area, and this problem is remarkable.

  In addition, a display unit has been developed in which a holder for holding an electronic circuit board is provided on a separate member from the holder for holding the liquid crystal module. When the holder is composed of two members, there is a problem that the number of parts of the display unit increases and the number of assembly processes increases. In addition, since the holder for holding the electronic circuit board is also fixed from the back side of the design panel with the design surface in contact with a jig or the like, there is a problem that the design surface is more easily damaged during the fixing operation. .

  In addition, electronic devices have been developed in which a display unit functions as an operation input unit by providing a touch panel integrated with a cover panel. The display part of such an electronic device is mounted on an electronic circuit board by providing a sheet metal member for electrical grounding (so-called “ground”) on a separate member from the holder, and discharging static electricity generated by the operation of the touch panel to the sheet metal member. In addition to protecting electronic parts such as integrated circuits (ICs) from static electricity, noise generated in the circuit is reduced. When a sheet metal member for grounding is provided in a separate member from the holder, there is a problem that the number of parts of the display unit is further increased. Further, since this sheet metal member is also fixed from the back side of the design panel in a state where the design surface is in contact with a jig or the like, there is a problem that the design surface is more easily damaged during the fixing operation.

  In addition, an electronic device has been developed in which a substantially plate-like display unit is assembled separately from the electronic device body, and this display unit is attached to the front opening of the electronic device body. In this case, as described above, the conventional electronic device has a liquid crystal module, a holder, an electronic circuit board, and the like fixed to the back surface of the design panel, so that the contents of the display unit (the liquid crystal module, the holder, the electronic circuit board, etc.) are displayed. From the viewpoint of preventing the display from being viewed from the back side of the part, the back part of the display part is covered with a sheet metal member (so-called “front chassis”) along the front opening of the electronic device body, or the back part of the display part is covered A substantially plate-shaped resin member (so-called “rear panel”) is added. When a front chassis made of sheet metal is provided, there is a problem that the weight of the entire electronic device increases. On the other hand, when the rear panel is provided, there is a problem in that the number of parts of the display unit increases due to the rear panel as a separate member from the design panel. Further, since this rear panel is also fixed from the back side of the design panel in a state where the design surface is in contact with a jig or the like, there is a problem that the design surface is more easily damaged during the fixing operation.

  The present invention has been made to solve the above-described problems, and can prevent the design surface of the design panel from being damaged when the display unit is assembled, and the number of parts of the display unit can be reduced. It is an object to provide an electronic device that can be reduced. Moreover, it aims at providing the manufacturing method of this electronic device.

That is, the liquid crystal module 1 and the cover panel 2 may be bonded together and at least one of the liquid crystal module 1 or the cover panel 2 may be bonded to the surface portion of the holder 3. The liquid crystal module 1 may be one in which the coating on the side surface portion and the back surface portion is removed and the contents (liquid crystal panel, light guide plate, backlight, etc.) are exposed.

  Further, the electronic device 100 may have a structure in which the touch panel is removed. In this case, the touch panel electrode, the wiring between the touch panel electrode and the electronic circuit board 4, and the touch panel control circuit are unnecessary. Further, since a structure for releasing static electricity is not required, the arm portion 35 is removed from the holder 3 and screws for screwing to the chassis are removed, so that the number of parts of the entire electronic device 100 can be further reduced. .

  Further, the fixing of the electronic circuit board 4 to the back surface of the holder 3 is not limited to screwing.
