Light metal/CFRP-made structural members which are characterized in that they are structural materials in which a CFRP material is stuck to the surface of a light metal material via an adhesive agent layer of thickness at least 10 mum and up to 500 mum, and the volume resistivity of the adhesive agent layer between said metal material and said CFRP material is at least 1x1013 OMEGA.cm and, furthermore, the adhesive strength at room temperature is at least 15 MPa. In accordance with the present invention, since conventional light metal/CFRP structural materials can be made lighter and, furthermore, since the resistance to galvanic corrosion is outstanding and it is possible to markedly enhance the strength and the impact energy absorption performance, the development of applications and large-scale expansion into new fields becomes possible. Weight reduction and enhancing the durability and reliability of structures also makes a considerable contribution in terms of environmental protection.

A cast-in anchor system for anchoring objects to concrete structures. The preferred system uses an extruded cast-in anchor and an extruded bolt retainer. The cast-in anchor is embedded within concrete with a face left exposed. The bolt retainer has a bolt inserted through it and is placed within an anchor channel on the exposed face of the cast-in anchor. The bolt retainer allows for use of an industry-standard bolt and prevents the bolt from rotating once the bolt-head is seated against it. The cast-in anchor and the bolt are positioned along the length of the anchor channel, with a threaded portion of the bolt extending out of the anchor channel. A workpiece is placed over the threaded portion of the bolt and a nut is tightened. Tightening the nut causes locking surfaces on the bolt retainer to engage with corresponding surfaces on the anchor channel which prevents the bolt retainer from exiting the anchor channel.

Disclosed are a liquid crystal display (LCD) device and a method for manufacturing the LCD device. The LCD device has a substrate including a display region and a pad region located in a periphery of the display region, the display region having a transparent electrode, the pad region having a pad electrode. The transparent electrode and the pad electrode are formed from the same layer. A reflective electrode having a transmission window exposing a portion of the transparent electrode is formed on the transparent electrode. The manufacturing process can be simplified because the transparent electrode is directly connected to the reflective electrode. Since the pad electrode is formed of the same layer as the transparent electrode, no metal corrosion occurs to thereby increase the pad reliability during COG bonding.
