| 1. A display panel device comprising:
a display panel with a screen; and
a front sheet that is glued on a front face of the display panel, wherein
the front sheet includes a front portion having a plane size that is larger than a plane size of the display panel and a rear
portion that contacts the front portion,
the front portion is constituted of plural layers, each layer having the same plane size and a different function,
the front portion is coupled to the front face of the display panel through the rear portion,
the rear portion has a plane size that is larger than a plane size of the screen and smaller than the plane size of the display
panel,
a layer of the plural layers that contacts the rear portion is an electromagnetic wave shielding layer that is configured
to shield electromagnetic waves radiated from the display panel,
the rear portion is formed from a single material that has a higher adhesion to the electromagnetic wave shielding layer than
to the front face of the display panel, and
a part of the electromagnetic wave shielding layer extends beyond the display panel in a plane view so as to enable contact
between the electromagnetic wave shielding layer and an external conductor at an extended portion of the electromagnetic wave
shielding layer.
