Claim 8:
9. A display device comprising:
a first substrate comprising a first transparent substrate and a pixel electrode;
a second substrate comprising a second transparent substrate and a common electrode;
a third transparent substrate attached to the second transparent substrate;
a liquid crystal layer located between the first substrate and the second substrate and containing a polymer and a liquid crystal molecule; and
a light emitting module comprising a light source, a light guide and a wiring board, wherein
the light source is provided between the first substrate and the wiring board,
the light guide is provided between the light source and a side surface of the second transparent substrate, and between the light source and a side surface of the third transparent substrate,
at least one of the first substrate and the second substrate comprises first light-shielding portions arranged in a first direction, second light-shielding portions arranged in a second direction intersecting with the first direction, and third light-shielding portions surrounded by the first light-shielding portions and the second light-shielding portions, and
when a width of each of the first light-shielding portions in the first direction is defined as Lxn, a width of each of the third light-shielding portions in the first direction is defined as Lxw, a width of each of the third light-shielding portions in the second direction is defined as Lyw, an interval between the first light-shielding portion and the third light-shielding portion in the first direction is defined as Sxn, and an interval between the second light-shielding portion and the third light-shielding portion in the second direction is defined as Syn,
a duty ratio Dx shown by {Lxn/(Sxn+Lxw+Lxn)}×{Syn/(Syn+Lyw)}+{(Lxn+Lxw)/(Sxn+Lxw+Lxn)}×Lyw/(Syn+Lyw) is less than or equal to 0.03.
