Claim:
1. A display device, comprising: a display panel and a module at the back side of the display panel, the module comprising a back plate and a mold frame, wherein, the mold frame is provided between the back plate and the display panel, wherein, the display device further comprises a magnetic device, and the display panel and the mold frame are attached to each other and detached from each other through the magnetic device, wherein the magnetic device comprises a magnetic force adjustable member for adjusting attraction between the display panel and the mold frame, wherein the magnetic force adjustable member comprises one or more electromagnetic coils formed at corresponding positions on the display panel, wherein, when the electromagnetic coils are powered on, they generate magnetic force to allow the display panel and the mold frame to attract mutually; and when the electromagnetic coils are powered off, they stop generating magnetic force to allow the display panel and the mold frame to separate from each other, wherein each of the electromagnetic coils comprises a plurality of layers of metal pattern, a passivation layer is formed between two adjacent layers of metal pattern, two adjacent layers of metal pattern are interconnected through a via hole formed in the passivation layer, and among the plurality of layers of metal pattern, a first layer of metal pattern and a last layer of metal pattern are connected with two electrodes of a power supply through leads respectively, wherein the display panel is a liquid crystal display panel which comprises a first substrate and a second substrate arranged opposite to each other, wherein the plurality of layers of metal pattern are formed in the first substrate and/or the second substrate, and wherein the magnetic device comprises one or more magnets which are fixedly attached to the display panel, overlapping with the plurality of layers of metal pattern of the electromagnetic coils and provided between the display panel and the mold frame, and the magnets are attracted to the mold frame through a magnetic field they generate so that the display panel is fixedly attached to the mold frame through the magnets.
