摘要： The present invention relates to a core/shell structured quantum rod and, specifically, to a core/shell structured quantum rod with maximized luminescence efficiency. Characteristics of the present invention are that: the core of the core/shell structured quantum rod is formed by mixing two semiconductor particles; and the shell which covers the core is formed by one semiconductor with bigger band gap among two semiconductors. Through the above characteristics, band gap difference between the core and shell is reduced, thereby electrons and positive holes directly related to luminescence of the core/shell structured quantum rod can be existed in a stable state; and high luminance efficiency, high luminance clarity, and high chemical stability can be achieved. In addition, the core/shell structured quantum rod of the present invention forms: the core into alloy semiconductor particles in which cadmium sulfide (CdS) semiconductor particles and zinc sulfide (ZnS) particles are mixed; and the shell into zinc sulfide (ZnS) semiconductor particles, thereby blue color having 450-480 nm color wave can be performed.

摘要： A quantum rod light emitting display device according to an aspect of the present invention includes a display panel including a quantum rod layer on which a plurality of quantum rods formed between a first substrate and a second substrate are arranged and a polarizing plate placed on the display panel and composed of a quarter wave plate (QWP) layer and a PVA layer displayed as the following chemical formula1. The PVA layer transmits only light linearly polarized in a first direction and the QWP layer is placed on the bottom of the PVA layer and circularly polarizes the linearly polarized light or linearly polarizes light reflected by the display panel in a second direction. According to this, as a polarizing plate including the PVA layer formed of hydrophobicity is applied, the transmittance of the plate can be improved and night visibility can be improved so that the efficiency of light from a backlight can be maximized.
