Abstract:
1. A quantum rod light-emitting display device comprising: a display panel including a first substrate, a second substrate opposite to the first substrate, and a quantum rod layer formed between the first substrate and the second substrate and containing quantum rods, wherein the quantum rods in the quantum rod layer are arranged in one direction; and a polarizer disposed on the display panel at the first substrate and including a quarter wave plate (QWP) layer and a polyvinyl alcohol (PVA) layer, the PVA layer includes a material expressed by Formula 1, and the PVA layer formed on the QWP layer, wherein X denotes polyethylene, and each of m and l is an integer ranging from 1 to 10000, wherein the PVA layer transmits external light linearly polarized in a first direction, and wherein the QWP layer is disposed under the PVA layer so that the QWP layer is disposed closer to the first substrate than the PVA layer, and the QWP layer circularly polarizes the light linearly polarized in the first direction and linearly polarizes light reflected by the display panel in a second direction so that the external light is extinguished by the polarizer after being reflected by the display panel.
