Abstract
A plurality of semiconductor chip mounting areas are arranged in series on the top surface of the lower edge section of the lower glass substrate of a liquid crystal display panel. In the semiconductor chip mounting areas, signal input electrode terminals are provided in a cascade. The signal input electrode terminals are connected to each other by means of input wires each having an inside semiconductor chip mounting area junction section and an outside semiconductor chip mounting area junction section.
Claims14
A connection structure of a display panel and a wiring board, comprising:
- a display panel which has a display area and is composed of a plurality of semiconductor chip mounting areas, output wires that are formed so as to correspond to said semiconductor chip mounting areas respectively and supply driving signals to said display area, first input wires, and second input wires, each of said first input wires having an electrode terminal located inside each of said semiconductor chip mounting areas and an input terminal located outside each of said semiconductor chip mounting areas, and said second input wires having junction sections for connecting electrode terminals respectively located inside adjacent ones of said semiconductor chip mounting areas with each other, and input terminals arranged near outside the one located at one end of said semiconductor chip mounting areas;
- and
- a wiring board including connection wires connected to the input terminals of said first input wires arranged so as to correspond to said plurality of semiconductor chip mounting areas respectively and connection wires connected to said input terminals of said second input wires.
A connection structure of a display panel and a wiring board, comprising:
- a display panel which has a display area and is composed of a plurality of semiconductor chip mounting areas, output wires that are formed so as to correspond to said semiconductor chip mounting areas respectively and are for supplying driving signals to said display area, a plurality of electrode terminals arranged inside each of said semiconductor chip mounting areas, and a plurality of input wires that are connected to the corresponding ones of said electrode terminals and run concentrically from the upper-stage side to lower-stage side of each of said semiconductor chip mounting areas without crossing each other in such a manner that their arrangement order is reversed with respect to the upper-stage side and the lower-stage side;
- and
- a wiring board including connection wires connected to the input terminals of said input wires arranged so as to correspond to said plurality of semiconductor chip mounting areas respectively and connection wires for connecting the ones of said input terminals located in said semiconductor chip mounting areas on the lower-stage side with the electrode terminals located in said semiconductor chip mounting areas on the upper-stage side.
