摘要:
A television receiver employs a liquid crystal display panel mounted in a unit which can be set into either a closed position in which the display panel is disposed within a recessed portion of the case of the television set, and an opened position in which ambient light passes through the display panel to be reflected from a mirror towards the viewer. In conjunction with this arrangement, operating control members are positioned to facilitate one-hand operation of the receiver, and the largest circuit components and batteries are positioned with respect to the display panel and control members such as to minimize the overall size of the receiver.

摘要:
A color filter is laminated via a resin layer on an electroluminescence device. The resin layer includes silicone resin as its main ingredient while having a thickness of 2 to 100 .mu.m. Thereby, possible color dislocation and reduction of the angle of visibility attributed to the gap between the electroluminescence device and the color filter are prevented. Furthermore, possible damage, dielectric breakdown, pixel dropout, and line defect due to the contact between the electroluminescence device and the color filter are reduced. A surface of the resin layer is changed in condition to make the resin layer have a lipophilic property to facilitate application of a material of the color filter thereto.
摘要:
A vapor deposition apparatus for depositing thin film on substrates in which solid starting materials are used. In this apparatus, a carrier gas flows up and down in the same direction as gas convection, such that the effect of gas convection is minimized and film thickness and impurity concentration are uniform over the substrate surface. This uniformity is achieved by orienting a main reaction tube in a vertical direction, attaching two branch reaction tubes at the top of the main reaction tube, and venting carrier gas out the bottom of the main reaction tube. Alternately, the main reaction tube can be oriented horizontally, with the substrates being carried on a holder within a container having pores on its top and bottom.

A thin film EL device having a double-insulated structure and comprising an emitting layer made of an alkaline-earth sulfide as its host material and doped with Eu.sup.2+ for providing luminescent centers. The emitting layer has a Eu concentration of 0.15 to 0.75 atm. % and a controlled thickness of at least 1.3 .mu.m to impart hysteresis to the brightness vs. applied voltage characteristics of the device.

A method for fabricating an electroluminescence display device is disclosed. The fabricating method includes steps of forming at least one transparent front electrode on a transparent substrate, forming a lower electrically insulating layer on the front electrode, forming an emitting layer of an electroluminescent material on the lower electrically insulating layer, forming an upper electrically insulating layer on the emitting layer, and forming at least one rear electrode on the upper electrically insulating layer. In the fabricating method, at least one of the lower and upper electrically insulating layers is composed of at least one film of Si.sub.x N.sub.y O.sub.z :H, and the si.sub.x N.sub.y O.sub.z :H film is formed by the plasma chemical vapor deposition method.
