Abstract
A pixel substrate of a liquid crystal display device of the present invention are equipped with gate bus lines, reference signal lines, gate signal input terminals, a reference signal trunk line, and reference signal input terminals. The reference signal trunk line is formed so as to run along all side edges of the pixel substrate except the left side edge which is on the gate signal input side, outside a display area of the pixel substrate (an area corresponding to a display area of a liquid crystal panel when completed), and is connected with every reference signal line. A sealing member for making the pixel substrate and a counter substrate adhere to each other is provided so as to be positioned on the reference signal trunk line 7.
Claims14
A liquid crystal display device, comprising:
- a first substrate having a plurality of gate bus lines, and a plurality of reference signal lines provided parallel with said gate bus lines;
- a second substrate having a plurality of source bus lines provided so as to cross said gate bus lines, said second substrate facing said first substrate with a predetermined gap therebetween;
- a sealing member for making said first and second substrates adhere to each other;
- and
- a peripheral metal film formed through the same step through which said gate bus lines are formed, said peripheral metal film being positioned along three side edges of said first substrate, said three side edges being the side edges of said first substrate other than one side edge thereof on a gate signal input side,
- wherein parts of said sealing member along said three side edges are positioned on said peripheral metal film.
A liquid crystal display device, comprising:
- a first substrate having a plurality of gate bus lines, and a plurality of reference signal lines provided parallel wit h said gate bus lines;
- a second substrate having a plurality of source bus lines provided so as to cross said gate bus lines, said second substrate facing said first substrate with a predetermined gap therebetween;
- a sealing member for making said first and second substrates adhere to each other;
- and
- a plurality of island-like metal films provided between said gate bus lines, on a gate signal input side of said first substrate, through the same step through which said gate bus lines are formed,
- wherein parts of said sealing member formed on the gate signal input side of said first substrate are positioned on said island-like metal films.
