An embodiment of the invention discloses a circuit repair structure and method, and aims to repair an open circuit formed at the intercrossing position of electric wires extending along different directions on a thin film transistor array substrate. The circuit repair structure comprises a repair wire and a protection pattern. The repair wire extends towards the same side of the electric wires at which the open circuit point located and connects two ends of the open circuit point. The repair wire penetrates another electric wire crossed the electric wire at which the open circuit located. The protection pattern is arranged between the repair wire and the electric wire that the repair wire crosses.

The invention relates to a method of preparing carbon fibers through crosslinked reaction of boron trichloride and polyacrylonitrile precursors. In the method, the boron-nitrogen bonds are formed by the reaction of the boron trichloride and unsaturated functional groups such as cyan in polyacrylonitrile precursors, the boron is uniformly introduced in the fiber, the chemical crosslinking of the polyacrylonitrile precursors is also realized, the crosslinked precursors are carbonized under the nitrogen protection and graphitized under the argon protection, and the original air preoxidation process is replaced. Compared with unmodified fiber obtained through air preoxidation, the release of the highly toxic gas such as hydrogen cyanide in the pyrolysis tail gas is greatly reduced, and the modulus of the carbon fiber is obviously improved. In the method, the process steps are not increased, the uniform chemical modification of boron is realized, the boron introduced by bonding can keep to the graphitization stage, no influence can be caused on the graphitization process, the production cost is low, and the industrialized production is convenient.

The invention provides a liquid crystal display device which comprises a first substrate, a second substrate and sealing glue, wherein the first substrate and the second substrate are relatively arranged; the sealing glue is arranged between the first substrate and the second substrate for adhering the first substrate and the second substrate; the first substrate is provided with a driving line and a first substrate common electrode toward the direction of the second substrate; the second substrate is provided with a second substrate common substrate toward the direction of the first substrate; a plurality of conductive particles are distributed into the sealing glue; the sealing glue is divided into a first sealing glue area and a second sealing glue; the conductive particles in the first sealing glue area are contacted with the first substrate common electrode and the second substrate common electrode; the conductive particles in the second sealing area are only contacted with the second substrate common electrode; a conductive housing layer is also arranged in the second sealing glue area, and positioned between the conductive parts and the driving line; and a first insulating layer is also arranged between the conductive housing layer and the driving line. With the adoption of the liquid crystal display device, the problems that the yield is reduced due to the discharging of the top ends of the conductive particles can be prevented.
