1. A liquid crystal display device comprising:
a display region for displaying an image; and
a frame region surrounding the display region,
the liquid crystal display device sequentially comprising from a viewing surface side toward a back surface side: a first polarizing plate; a first substrate provided with a switching element connected to a gate line and a source line; a liquid crystal layer; a second substrate; and a second polarizing plate,
in the frame region, the first substrate sequentially comprising from a viewing surface side toward a back surface side a glass substrate, a reflectance-reducing layer, and a metal line layer that overlaps the reflectance-reducing layer and includes at least one of a gate line layer provided with the gate line or a source line layer provided with the source line,
the reflectance-reducing layer having a lower viewing surface side reflectance than the metal line layer.
