Abstract:
1. An active matrix type liquid crystal display device comprising: a liquid crystal layer interposed between a first substrate and a second substrate; a plurality of gate lines formed on the first substrate; a plurality of drain lines disposed on the first substrate in matrix form to intersect the plurality of gate lines; thin film transistors formed on the first substrate and respectively disposed to correspond to intersections of the gate lines and the drain lines; and a sealing material which causes the first substrate and the second substrate to adhere to each other along their peripheral portions, wherein each of the drain lines is connected to a metal material formed in the same process as the gate lines on a display-area side of the sealing material, is led under the sealing material as a metal material layer formed in the same process as the gate lines, and in an external-connection-terminal-side area outside the sealing material, is led from the metal material layer formed in the same process as the gate lines and is connected to an external connection terminal via a metal material layer formed in the same process as the drain lines, and an organic film formed as a protective film for the thin film transistor has an opening in an area under the sealing material in which each of the drain lines is led as the metal material layer formed in the same process as the gate lines, the sealing material in the area being adhered to an inorganic insulating film.
