Zusammenfassung:	To provide a display device suitably used in a use mode with low consumption power by selecting a display method using separate pixels with different arrangement or resolution depending on a difference of display objects.SOLUTION: A first display panel 10 (preferably reflection type or semi-transmission type liquid crystal display device) including a non-light-emitting display element that performs display by having an optical modulation element reflect external light, an opaque light diffusion layer 30 with a light-transmitting property, and a second display panel 20 (preferably organic EL display) including a light-emitting display element that performs display by directly modulating a light-emitting element are overlapped from a display observation side.SELECTED DRAWING: Figure 1 【課題】表示対象の相違に応じて、配列や解像度の異なる互いに別々の画素を有する表示方式を選択し、消費電力の低減を図った使用形態に好適な表示装置を提案する。【解決手段】表示の観察側から、光変調素子が外光を反射させて表示を行なう非発光表示素子からなる第１表示パネル１０（反射型または半透過型の液晶表示装置が好適）、透光性を持つ不透明な光拡散層３０、発光素子が直接変調し表示を行なう発光表示素子からなる第２表示パネル２０（有機ＥＬディスプレイが好適）、が重畳されてなる構成。【選択図】図１
