An optical path control device and a display device including the same are discussed. The optical path control device can include a first substrate, a first electrode disposed on the first substrate, a second electrode disposed on the first substrate, a second electrode disposed under the second substrate, and a photoconversion layer disposed between the first electrode and the second electrode. The photoconversion layer can include a partition portion and a receiving portion that are alternately arranged, and the receiving portion can include suspended particles. The first electrode can include a first auxiliary electrode disposed on a first area of the first substrate and a second auxiliary electrode disposed on a second area of the first substrate.

Optical path control device and display device including the same

A viewing angle control film and a display device comprising the same are discussed. The viewing angle control film can include a first electrode, a second electrode facing away from the first electrode, a light conversion layer disposed between the first electrode and the second electrode, and a controller configured to adjust a viewing angle of the light conversion layer by controlling a voltage applied between the first electrode and the second electrode. The light conversion layer can include a plurality of partition walls disposed to be spaced apart between the first electrode and the second electrode, a plurality of containing portions disposed between the partition walls and arranged at regular intervals along the first electrode, and light blocking particles provided in each of the plurality of containing portions. The controller applies a pulse voltage in a share mode that operates in a wide viewing angle.

Viewing angle control film and display device comprising the same

A light path control device and an electronic device including the light path control device, which reduce color shift at a side viewing angle, are provided. The light path control device can include a light path control layer including first, second and third light control layers, and a transparent base member coupled to the first light control layer or the third light control layer. The third light control layer can have a refractive index which is lower than a refractive index of the second light control layer. The light path control layer can include a first refractive surface disposed between the first light control layer and the third light control layer, and a second refractive surface and a third refractive surface disposed between the second light control layer and the third light control layer.
