Abstract:
1. A liquid crystal display device comprising: a lower pad electrode connected to a signal line of a liquid crystal display panel; one or more insulating layers formed on the lower pad electrode; a first and a second main contact holes passing through the one or more insulating layers to expose both ends of the lower pad electrode; a plurality of minute holes passing through the one or more insulating layers to expose the lower pad electrode between the first and the second main contact holes in a plan view; and an upper pad electrode electrically connected to the upper portion of the lower pad electrode via the minute holes and the first and the second main contact holes, wherein an area of each of the first and the second main contact holes is substantially larger than an area of each of the plurality of minute holes and has a width substantially identical to that of the lower pad electrode.
