    Abstract: 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.

    Abstract: A display device includes a substrate and pixels arranged on the substrate in a matrix form. The substrate includes a display area in which the pixels are arranged and a non-display area disposed adjacent to a side of the display area. Each pixel includes a cover layer that extends in a row direction that includes a sidewall portion connected to the substrate and a cover portion spaced apart from the substrate and connected to the sidewall portion to define a tunnel-shaped cavity on the substrate. A width of the sidewall portion between adjacent pixels is less than a width of the sidewall portion disposed at an outermost position, and the cover layer seals one side of the tunnel-shaped cavity in the pixels arranged in a first row and a last row.

An exemplary display panel has a substrate; a pixel electrode formed on the substrate; a first black matrix and a second black matrix each disposed on the substrate; and a supporting member disposed on the substrate over the pixel electrode and the black matrix, the supporting member shaped so as to form a microcavity between the pixel electrode and the supporting member, the microcavity having an upper surface proximate to the supporting member and a lower surface opposite the upper surface. The microcavity has one end positioned over the first black matrix, and another end opposite the first end and positioned over the second black matrix; the lower surface of the microcavity has first and second channels disposed therein, the first channel positioned over the first black matrix, and the second channel positioned over the second black matrix.

    Abstract: A method of manufacturing a liquid crystal display includes: forming a sacrificial layer by stacking a non-photosensitive resin; initiating formation of an etch stop layer on the sacrificial layer; forming a photoresist pattern; completing the etch stop layer using the photoresist pattern; ashing the photoresist pattern and the sacrificial layer by using the completed etch stop layer as a mask; forming a microcavity by removing the sacrificial layer; and forming a liquid crystal layer in the microcavity. The horizontal area occupied by the sacrificial layer is reduced by forming the common electrode or the etch stop layer at an upper side, thereby increasing the aperture ratio. Further, the vertical electric field is generated without distortion by horizontally forming the common electrode on the sacrificial layer and forming no common electrode on the sidewall thereof.
