Provided is a head mounted display device including a housing for providing a darkroom space, a display module in the housing and to display an image, and an optical lens for expanding the image to provide the image to a user. The display module includes a destructive interference structure which removes the image reflected from the optical lens without reflecting the image again.

Display module and head mounted display device

According to one or more embodiments of the present invention, a display apparatus includes: a substrate; a display unit which is formed on the substrate and includes an emission area and a non-emission area; a first coating layer which is formed on the display unit and has an uneven area formed on the emission area; a first blocking layer which is formed on the non-emission area of the first coating layer; and a second blocking layer which is formed on the first blocking layer and prevents reflection of external light.

Display apparatus and method of manufacturing the same

In one aspect, a cathode including the first metal layer, the transparent conductive layer formed on the first metal layer, and the second metal layer formed on the transparent conductive layer is applied to the organic light emitting device and thicknesses of the first metal layer, the transparent conductive layer, and the second metal layer are controlled so that the external light reflection of the organic light emitting device is prevented. The cathode may further include the third metal layer formed on the second metal layer.

Thin film encapsulation for a flat panel display device and a method of manufacturing the thin film encapsulation structure. The thin film encapsulation structure of the flat panel display device includes thin film layers covering a display unit formed on a substrate, wherein the thin film layers comprise a plurality of inorganic layers and a hexamethyldisiloxane (HMDSO) layer interposed between the inorganic layers. Accordingly, as multiple layers of the thin film encapsulation structure may be formed in a single chamber, the manufacturing process may be simplified, and also, as the HMDSO layer, which is flexible, absorbs stresses, a risk of cracks occurring may also be reduced.
