Abstract

A liquid crystal display panel includes an active matrix substrate, a counter substrate, a liquid crystal layer, and a sealant. The counter electrode is opposed to the active matrix substrate. The liquid crystal layer is provided between the active matrix substrate and the counter substrate. The sealant, which surrounds the liquid crystal layer between the active matrix substrate and the counter substrate, joins the active matrix substrate and the counter substrate and seals the liquid crystal layer. A portion of the surface on the liquid crystal layer side of the active matrix substrate which is located at the periphery of the liquid crystal display panel is flat.

Dependent claims

A display panel comprising:

a first substrate;
a second substrate opposed to the first substrate;
a display medium layer provided between the first substrate and the second substrate;
a sealant surrounding the display medium layer between the first substrate and the second substrate so as to join the first substrate and the second substrate and sealing the display medium layer;
wherein
the first substrate includes a mark located at a periphery of the display panel outside of the sealant and arranged on a side of the display medium layer, and a flattening film which is arranged on the side of the display medium layer to cover a surface of the first substrate;
the flattening film includes a sealing exposing portion arranged around the display panel so as to expose the sealant to an outside;
and
the mark is arranged on a portion between the sealing exposed opening and an edge side of the flattening film.
