To provide a display apparatus and an electronic apparatus capable of achieving both a force feedback function and a tactile function and having high strength.SOLUTION: A display apparatus according to the present invention comprises a display panel, a touch panel, a spacer, a tactile panel, and a piezoelectric actuator. The touch panel is arranged on the display panel and comprises a first main surface on the display panel side and a second main surface opposite to the first main surface. The tactile panel is arranged on the spacer and comprises a third main surface facing the second main surface with a gap therebetween and a fourth main surface opposite to the third main surface. The piezoelectric actuator is arranged on the third main surface and generates vibrations. Assuming that the thickness from the second main surface to the fourth main surface is a first thickness and the thickness from the second main surface to the third main surface is a second thickness, the first thickness is not less than 0.5 mm and not more than 1.5 mm, and is not less than the thickness obtained by adding 0.3 mm to the second thickness and not more than the thickness obtained by adding 1 mm to the second thickness.SELECTED DRAWING: Figure 4 【課題】フォースフィードバック機能と触覚機能を両立させることが可能であり、高い強度を備える表示装置及び電子機器を提供すること。【解決手段】本発明に係る表示装置は、ディスプレイパネルと、タッチパネルと、スペーサーと、触覚用パネルと、圧電アクチュエータとを具備する。タッチパネルは、ディスプレイパネル上に配置され、ディスプレイパネル側の第１主面と、第１主面とは反対側の第２主面を有する。触覚用パネルは、スペーサー上に配置され、第２主面と間隙を介して対向する第３主面と、第３主面とは反対側の第４主面を有する。圧電アクチュエータは、第３主面上に配置され、振動を発生する。第２主面から第４主面までの厚みを第１厚みとし、第２主面から第３主面までの厚みを第２厚みとすると、第１厚みは０．５ｍｍ以上１．５ｍｍ以下かつ、第２厚みに０．３ｍｍを加算した厚み以上、第２厚みに１ｍｍを加算した厚み以下である。【選択図】図４
