Abstract
A display device including a display panel, and an anti-reflection layer on the display panel is provided. The anti-reflection layer includes a plurality of inorganic layers, the plurality of inorganic layers including a plurality of first inorganic layers having a first refractive index, and each including a silicon oxynitride (SiON), and a plurality of second inorganic layers having a second refractive index which is higher than the first refractive index, and each including a silicon oxynitride. Accordingly, it is possible to form an anti-reflection layer structure having low reflectance and high capping properties while being formed through a simple process, so that the display device may have improved durability and visibility.
Claims20
A display device comprising:
- a display panel;
- and
- an anti-reflection layer on the display panel, the anti-reflection layer comprising a plurality of inorganic layers comprising:
- a plurality of first inorganic layers having a first refractive index, and each comprising a silicon oxynitride (SiON);
- and
- a plurality of second inorganic layers having a second refractive index which is higher than the first refractive index, and each comprising a silicon oxynitride,
- wherein one of the plurality of first inorganic layers is closest to the display panel from among the plurality of first inorganic layers and the plurality of second inorganic layers.
A display device comprising:
- a display panel;
- and
- an anti-reflection layer on the display panel, the anti-reflection layer comprising a plurality of inorganic layers comprising:
- a plurality of first inorganic layers, each comprising a silicon oxynitride (SiON);
- and
- a plurality of second inorganic layers, each comprising a silicon oxynitride,
- wherein, when an amount of oxygen with respect to a total amount of elements in the plurality of first inorganic layers is defined as a first oxygen content, and an amount of oxygen with respect to a total amount of elements in the plurality of second inorganic layers is defined as a second oxygen content, the first oxygen content is greater than the second oxygen content, and
- wherein one of the plurality of first inorganic layers is closest to the display panel from among the plurality of first inorganic layers and the plurality of second inorganic layers.
A tiling display device comprising a plurality of unit display devices along at least one direction, wherein each of the plurality of unit display devices comprises:
- a display panel;
- and
- an anti-reflection layer on the display panel, the anti-reflection layer comprising a plurality of inorganic layers comprising:
- a first inorganic layer having a first refractive index, and comprising a silicon oxynitride (SiON);
- and
- a second inorganic layer being in contact with any one of an upper surface or a lower surface of the first inorganic layer, and having a second refractive index which is higher than the first refractive index, and comprising a silicon oxynitride,
- wherein the first inorganic layer is closest to the display panel relative to the second inorganic layer.
