An embodiment of the present disclosure provides an upper electrode including a flat upper surface; a lower surface facing the upper surface; and a thickness from the upper surface to the lower surface, wherein the lower surface includes a first profile corresponding to the central area of the lower surface and having a first thickness change rate of −0.1 to 0; a third profile surrounding the first profile and having a third thickness change rate of −0.115 to −0.122; and a fifth profile surrounding the third profile and having a fifth thickness change rate of −0.003 to 0.003, wherein the first thickness change rate, the third thickness change rate, and the fifth thickness change rate are values obtained by dividing a change in thickness by a change in radius along a horizontal direction parallel to the upper surface from a center of the lower surface.

Semiconductor device fabrication apparatus

The present invention relates to an organic electroluminescence display and a fabricating method thereof enabling to simplify a manufacturing process and reduce a product cost by separating devices with a single insulating pattern. The present invention includes the steps of: forming a plurality of stripe type first electrodes on a substrate; forming an insulating layer on the substrate including the first electrodes; forming a lattice type first insulating pattern on a first area crossing with the first electrodes and a second area between the first electrodes by patterning the insulating layer; forming a second insulating pattern by removing an upper portion of a part of the first insulating pattern on the first area at least and an upper portion of the first insulating pattern on the second area; forming organic light-emitting layers on the first electrodes; and forming a plurality of second electrodes on the organic light-emitting layers.

Organic electroluminescence display and method of fabricating the same

Disclosed is a liquid crystal display having an improved characteristic of viewing angle by modifying a pixel electrode and a common electrode construction respectively. In a liquid crystal display, upper and lower substrates are opposed to each other and spaced from each other by a predetermined distance. A liquid crystal layer is interposed between the upper and the lower substrates. A pixel electrode is formed at a portion of an inner surface of the lower substrate corresponding to a pixel area, and the pixel electrode has an uneven surface including first convex portions and first concave portions. A common electrode is formed at a portion of an inner surface of the upper substrate corresponding to the pixel electrode, so as to form an electric field together with the pixel electrode. The common electrode has an uneven surface including second convex portions and second concave portions.

Liquid crystal display having uneven convex and concave portions in both pixel and common electrodes

An apparatus for and a method of remote controlling an operation of a vibration roller, capable of achieving the operation of vibration roller under a condition that no operator have a ride in the vibration roller. The apparatus includes a wireless transmitting unit, a wireless receiving unit, a control unit for controlling functional parts required for the operation of vibration roller, an operation switch unit, a forward/rearward running manipulating unit, a steering unit and an acceleration and stop manipulating unit.
