Liquid crystal display device

A liquid crystal display device comprising:

• a first substrate;
• a second substrate opposed to the first substrate;
• an annular seal located between the first substrate and the second substrate;
• and
• a liquid crystal layer sealed in a space surrounded by the first substrate, the second substrate, and the annular seal,
• wherein the first substrate comprises:
• a first metal layer including a plurality of scanning signal lines;
• a first insulating layer covering the first metal layer;
• a second metal layer including a plurality of video signal lines, the second metal layer being formed on the first insulating layer;
• a second insulating layer covering the second metal layer;
• a third metal layer including a plurality of common lines, the third metal layer being formed on the second insulating layer;
• a third insulating layer covering the third metal layer;
• an alignment layer arranged on the third insulating layer, the alignment layer contacting to the liquid crystal layer;
• and
• a display region where a plurality of pixels are formed, one of the plurality of pixels being defined by two of the plurality of scanning signal lines and two of the plurality of video signal lines,
• wherein at least one recessed groove is formed in the third insulating layer and is located at a region between the display region and the annular seal,
• wherein the at least one recessed groove is formed on a groove bottom member located above the second insulating layer,
• wherein a first transparent conductive film is disposed between the groove bottom member and the second insulating layer, and
• wherein a material of the first transparent conductive film is different from a material of the groove bottom member.
