Abstract
An active matrix LCD device includes a TFT panel, a counter panel and liquid crystal interposed therebetween. The TFT panel includes a plurality of scanning lines and a plurality of common lines formed in one layer and extending in a row direction, and a plurality of signal lines extending in a column direction. A coupling line for coupling the common lines together is disposed outside the pixel array of the TFT panel, such as in a TCP mounted on the TFT panel and mounting thereon a driver IC for driving the scanning lines.
Claims6
A liquid crystal display (LCD) device comprising a TFT panel, a counter panel and liquid crystal interposed therebetween, said TFT panel comprising:
- a transparent substrate;
- a plurality of scanning lines overlying said transparent substrate to extend in a row direction;
- a plurality of signal lines overlying said transparent substrate to extend in a column direction;
- a plurality of common lines each corresponding to one of said scanning lines to extend in said row direction parallel to said one of said scanning lines, said scanning lines and said common lines are formed in a single layer so that at least one of said scanning lines and at least one of said common lines are arranged consecutively in said column direction and alternating from each other in parallel;
- an array of pixels each disposed at an intersection between one of said scanning lines and one of said signal lines;
- and
- a coupling line extending in said column direction, said coupling line including a conductive paste or a conductive tape coupling said common lines together.
A liquid crystal display (LCD) device comprising a TFT panel, a counter panel, and liquid crystal interposed therebetween, said TET panel comprising:
- a transparent substrate;
- a plurality of scanning lines overlying said transparent substrate to extend in a row direction;
- a plurality of signal lines overlying said transparent substrate to extend in a column direction;
- a plurality of common lines each corresponding to one of said scanning lines to extend in said row direction parallel to said one of said scanning lines, said scanning lines and said common lines are formed in a single layer so that at least one of said scanning lines and at least one of said common lines are arranged consecutively in said column direction and alternating from each other in parallel;
- and
- an array of pixels each disposed at an intersection between one of said scanning lines and one of said signal lines,
- said TFT panel mounting thereon at least one driver block including a film member, a driver IC mounted on said film member for driving said scanning lines, and a coupling line for connecting said common lines together, said coupling line extending in a space between said film member and said driver IC.
