Abstract
A display device includes a light providing assembly to provide light, and a display panel to display an image using the light. The display panel includes a first substrate (FS), a second substrate (SS), a liquid crystal layer (LCL), a polarizing plate (PP), a first optical element (FOE), and a second optical element (SOE). The FS includes a pixel region (PR) and a non-PR (NPR) adjacent to the PR. The SS faces the FS. The LCL is disposed between the FS and SS. The PP is disposed between the FS and LCL, and includes grid polarizing layers. The FOE is disposed between the FS and PP, and is configured to redirect a fraction of the light propagating toward the NPR in a first direction. The SOE is disposed between the FOE and PP, and is configured to redirect the fraction of light propagating in the first direction toward the PR.
