FIELD: physics, optics.
SUBSTANCE: invention relates to display devices such as a liquid crystal display device. The display device comprises first and second substrates facing each other. The first substrate has a substrate body, a first group of interconnections provided on the substrate body, and a second group of interconnections with an insulating film situated between the groups of interconnections. A channel (27) is formed over the first group of interconnections (21, 23a) of the first substrate, which continues along the section of the outer periphery of the substrate and across the first group of interconnections (21, 23a). An underlying layer (27a) of metal is provided in the same layer as the second group of interconnections (23), under the channel (27), at least in regions where the channel (27) overlaps the first group of interconnections (21, 23a) when viewed from above.
EFFECT: reduced frame thickness and longer service life of the display panel.
