Abstract
A base chassis has projection parts. A surrounding part of an image display surface of a plasma display panel (PDP) is in contact with a contact part formed around an opening part of a front case. The projection parts are fixed to a chassis fixation part of the front case. The projection parts each have an elastic structure part which elastically deforms in response to a pushing force to the display surface of the PDP. An external force from a rear case side is transmitted to the chassis fixation part only, preventing impact to the PDP. When the PDP directly receives an external force from the front case side, the elastic structure part can elastically deform to alleviate the impact to the PDP. This can alleviate stress to the PDP when applied an external force from the front surface and the rear surface of the cases.
