Claim 17:
18. A transparent display panel, comprising:
a first substrate and a second substrate;
a liquid crystal layer located between the first substrate and the second substrate;
a light guide plate located on a side of the first substrate or the second substrate away from the liquid crystal layer, wherein the light guide plate has a first light guide plate surface away from the liquid crystal layer, a second light guide plate surface facing the liquid crystal layer, and a fifth light incident surface located between the first light guide plate surface and the second light guide plate surface;
a first light source assembly located on a side, where the fifth light incident surface is located, of the light guide plate; and
a first light guide bar located between the first light source assembly and the fifth light incident surface, wherein the first light guide bar has a first light guide bar surface facing the fifth light incident surface, a second light guide bar surface away from the fifth light incident surface, and a first light guide bar slope surface located between the first light guide bar surface and the second light guide bar surface, and an inner angle formed between the first light guide bar slope surface and the second light guide bar surface is less than or equal to 90 degrees,
wherein a distance between the first light guide bar surface and the second light guide bar surface is equal to a length difference between the second substrate and the first substrate in a direction perpendicular to the fifth light incident surface.
