Abstract: A liquid crystal display device includes a TFT substrate, a color filter substrate, liquid crystals, a transparent conductive film, a panel identification pad, and conductive paste. The color filter substrate is opposed to the TFT substrate and has a color filter. The liquid crystals are sealed between the TFT substrate and the color filter substrate. The transparent conductive film is located on a front surface side of the color filter substrate including a periphery of the color filter substrate. The panel identification pad is located on a terminal area that is a portion of the TFT substrate extending beyond the color filter substrate. The panel identification panel is conductive and connected to a ground potential. The conductive paste electrically connects the panel identification pad with the transparent conductive film located on the periphery of the color filter substrate.

Abstract: A liquid crystal display device includes: a first substrate which includes a display region, in which scan wirings and signal wirings intersecting with scan wirings are formed, and a frame region, which surrounds the display region, wherein a lead-out wiring extending from at least one of the signal wiring and the scan wiring and a ground electrode on an insulating layer covering the lead-out wiring are formed in the frame region; a second substrate, which faces the first substrate with interposing a seal, wherein a transparent conductive film is formed on a surface opposite to a side where the liquid crystal is provided; and a conductive member, which is formed to extend across the first substrate and the second substrate to electrically connect the transparent conductive film with the ground electrode, wherein the ground electrode overlaps with at least one of the lead-out wirings.
