Classification: CPC G | IPC G

Claim 0:
1. A display device comprising:
a light-emitting element;
a first substrate comprising a first transparent substrate, a scanning line, a signal line crossing the scanning line, a switching element electrically connected to the scanning line and the signal line, a grid-shaped insulating film located above the first transparent substrate and defining an opening, and a pixel electrode located in the opening and electrically connected to the switching element;
a second substrate comprising a second transparent substrate including a side surface facing the light-emitting element, and a common electrode overlapping the pixel electrode; and
a liquid crystal layer located between the first substrate and the second substrate, and including stripe-shaped polymers extending in a first direction and liquid crystal molecules, wherein
the insulating film is an organic insulating film and includes a pair of first transparent portions extending in the first direction and a pair of second transparent portions extending in a second direction crossing the first direction,
one of the first transparent portions overlaps the scanning line,
one of the second transparent portions overlaps the signal line,
the liquid crystal layer includes a first polymer in an area overlapping the first transparent portions of the insulating film and a second polymer in an area overlapping the opening in a planar view, and
a density of the first polymer is higher than a density of the second polymer.
