Furthermore, in the case that the shield electrode is disposed on a layer where a connecting pattern connecting between the touch electrode and the touch line is disposed, by maintaining an arrangement of the shield electrode on some area where the data line is overlapped and the touch electrode isn't disposed, thus an effect of a coupling reduction can be provided while maintaining a noise blocking performance of the shield electrode stably.

Abstract

A display device includes a display panel including a plurality of sub-pixel areas for respectively outputting light for displaying an image and a light travel-direction changing layer disposed on the display panel for diversifying and spreading travel directions of light emitted from each of the plurality of sub-pixel areas. The light travel-direction changing layer includes a plurality of refractive patterns respectively corresponding to the plurality of sub-pixel areas and arranged in a matrix form, and a light-scattering layer disposed around each of the plurality of refractive patterns and having a refractive index different from a refractive index of each of the plurality of refractive patterns. Due to the light travel-direction changing layer, light from each sub-pixel area is incident into each refractive pattern, is refracted at a boundary between each refractive pattern and the light-scattering layer, and is scattered in the light-scattering layer. Thus, the light emits out of the display device in the diversified and spread travel directions.
