Abstract
Description
図1は、実施の形態1における表示装置の構成を示す分解斜視図である。図2は、表示装置の構成を示す平面図である。図3は、表示装置の構成を示す断面図であり、図2において示されたX−X’における断面を示す。
表示装置にタッチパネル3が設けられていない場合であっても、実施の形態1と同様の効果が生じる。タッチパネル3が設けられていない場合、保護板1Aは、表示パネル6の表示面6Aに対して向かい合って設けられる。つまり、実施の形態1の変形例において、表示装置の前面10は、表示パネル6の表示面6Aである。保護板1Aは、表示装置の前面10である表示パネル6の表示面6Aを保護する。
実施の形態2における保護板および表示装置を説明する。なお、実施の形態1と同様の構成および動作については説明を省略する。
実施の形態3における保護板および表示装置を説明する。なお、実施の形態1または2と同様の構成および動作については説明を省略する。
