Abstract
There is provided a display apparatus that can improve the protective function and light utilization efficiency of organic EL devices and that has a simple structure. The display apparatus includes a plurality of organic EL devices formed on a substrate and a protective layer formed on the organic EL devices. The protective layer includes a first protective layer made of an inorganic material, a second protective layer made of a resin and having a microlens formed therein, and a third protective layer made of an inorganic material.
Claims3
A display apparatus comprising a plurality of organic EL devices each including a pair of electrodes and an organic compound layer that includes a light-emitting layer and is sandwiched between the pair of electrodes, the plurality of organic EL devices being formed on a substrate;
- and a protective layer formed on the plurality of organic EL devices, wherein the protective layer includes a first protective layer made of an inorganic material, a second protective layer formed on the first protective layer and made of a resin material, and a third protective layer formed on the second protective layer and made of an inorganic material;
- a microlens configured to condense at least part of light emitted at the light-emitting layer is formed in the second protective layer;
- and
- the microlens has an elongated semicylindrical shape that extends so as to cover a plurality of organic EL devices.
