Liquid crystal display device including trunk lines

摘要

In the present liquid crystal display device, a conventional first auxiliary capacitance trunk line 430 is formed to be narrow, and a second auxiliary capacitance trunk line 440 is additionally provided and disposed at the closest position to the periphery of a substrate. Thus, a shift register can be distanced from the periphery of the substrate without increasing a frame area as a whole, so that the shift register is not overlaid with a seal material. Moreover, the extent of an area overlaid with a seal material within a wiring area for providing signals to the shift register can be reduced.

主权项

1. An active-matrix liquid crystal display device comprising:
a first substrate including a display area in which pixel formation portions configured to produce an image to be displayed are arranged in a matrix; a second substrate opposed to the first substrate; and a liquid crystal layer sealed between the first and second substrates by a predetermined seal material; wherein the first substrate includes:
video signal lines configured to transmit signals to represent the image to be displayed;scanning signal lines crossing the video signal lines;auxiliary lines extending in parallel with the scanning signal lines;a scanning signal line driver circuit including a group of circuits configured to selectively drive the scanning signal lines;a first auxiliary trunk line extending in an arrangement direction of the auxiliary lines and electrically connected to the auxiliary lines, the first auxiliary trunk line being located outside of the display area and directly between the scanning signal line driver circuit and the display area; anda second auxiliary trunk line extending in the arrangement direction of the auxiliary lines and electrically connected to the auxiliary lines, the second auxiliary trunk line being located between the scanning signal line driver circuit and an edge of the first substrate that is opposite to the display area with respect to the scanning signal line driver circuit.
