Abstract: An optical film may include a first pattern layer having a first refractive index and including a base portion and a plurality of protrusions on the base portion x, and a second pattern layer disposed on the first pattern layer and having a second refractive index different from the first refractive index. Each of the protrusions may include n sub-protrusions (n is an integer of 2 or greater), which are stacked in a thickness direction of the base portion. Each of the n sub-protrusions may have a quadrilateral shape. A side surface of the protrusion defined by the n sub-protrusions may include at least one step portion. The optical film improves display quality of a display device in front and lateral directions.

Abstract: A display device includes a display area including a first light-emitting area and a second light-emitting area; a peripheral area adjacent to the display area; pixels which emit incident light; an encapsulation layer covering the pixels; a first color-converting pattern corresponding to the first light-emitting area and having a refractivity; a transmission pattern corresponding to the second light-emitting area and through which the incident light is transmitted; a low refractivity layer is in the display area and facing the encapsulation layer with each of the first color-converting pattern and the transmission pattern therebetween, the low refractivity layer including: a resin and a hollow particle which define a refractivity lower than the refractivity of the first color-converting pattern; and a first dam structure in the peripheral area and spaced apart from the display area, the first dam structure and the transmission pattern being portions of a same material layer.

Abstract: A display device includes a base layer, a first pixel transistor, a first gate line, a first data line electrically connected to the first pixel transistor, a first pixel electrode electrically connected to the first pixel transistor and overlapping the first data line in a plan view, and a porous layer. The porous layer is disposed between the first data line and the first pixel electrode and includes a matrix including a polymer resin and a plurality of void portions defined in the matrix. The display device is capable of displaying a sharp image because the porous layer alleviates or prevents a crosstalk between the first data line and the first pixel electrode.
