A display apparatus includes a plurality of pixel units and each pixel unit includes a substrate, a first electrode, a second electrode, an image display part and a protective layer. The first electrode is formed on the substrate. The second electrode is formed over the first electrode while interposing a first insulating layer therebetween to define a TSC (tunnel-shaped cavity) extending in a first direction between the first and second electrodes. The image display part is provided in the TSC to display an image according to an electric field generated by the first and second electrodes. The protective layer covers the second electrode and seals the TSC. The display apparatus having the above structure is manufactured by forming the first electrode, a sacrificial layer and the second electrode and forming the image display part by removing the sacrificial layer.

Display apparatus and manufacturing method thereof

A backlight unit includes a light source generating light, a light guide plate guiding the light in an upper direction, and an optical member disposed on the light guide plate to condense the light provided from the light guide plate in the upper direction. A top surface of the light guide plate includes a plurality of circular areas and a peripheral area around the circular areas. Each of the circular areas includes a central circular area and a ring area surrounding the central circular area. The optical member includes a first insulating layer disposed on the light guide plate and spaced apart from the light guide plate by predetermined distances in the ring areas and the peripheral area to define a plurality of cavities, and a second insulating layer disposed on the first insulating layer.

Backlight unit, display device including the same, and method of fabricating the backlight unit

An electrowetting display apparatus includes an array substrate, an opposite substrate, and an electrowetting layer. The array substrate includes a base substrate having a plurality of pixel areas and a plurality of pixel electrodes respectively arranged in each of the pixel areas. The pixel electrodes in each pixel area are spaced apart from each other at regular intervals and each have an island pattern shape.
