Display Apparatus

A display apparatus includes a substrate including a display area and a peripheral area outside the display area, a display element arranged on the substrate in the display area, an encapsulation layer arranged on the display element, a first insulating layer arranged on the encapsulation layer and including a first opening that corresponds to a light-emitting area of the display element, and a second insulating layer covering the first insulating layer. A second refractive index of the second insulating layer is greater than a first refractive index of the first insulating layer, and a side surface of the first insulating layer defining the first opening includes a staircase-shaped step. 提供了一种显示装置。该显示装置包括：基板，包括显示区域和在显示区域外部的外围区域；显示元件，布置在显示区域中的基板上；封装层，布置在显示元件上；第一绝缘层，布置在封装层上并且包括与显示元件的发光区域对应的第一开口；以及第二绝缘层，覆盖第一绝缘层。第二绝缘层的第二折射率大于第一绝缘层的第一折射率，并且第一绝缘层的限定第一开口的侧表面包括阶梯形台阶。
