Abstract	Korea Conformity Laboratories, 199, Gasandigital 1 ro, Geumcheon-gu, Seoul 153-803, Korea(Received October 16, 2014 ; revised October 28, 2014 ; accepted October 28, 2014)Abstract In this paper, in order to achieve slim and light liquid crystal display, we examine the optical conditionsthat can obtain uniform light with higher optical efficiency over whole light guide plate (LGP) through sim-ulation. Furthermore, to overcome the issues of hot spot in front of red, green, and blue light emitting diodes(RGB LEDs) source and non-uniform color mixing, we propose four shaped color mixing bars tied up withthe LGP and check the optical characteristics of the LGP with them by simulation. Consequently, we couldknow the optical conditions of improving optical efficiency and optical uniformity in the LGP through theoptical design. Also we confirmed that the issues of the hot spot and non-uniform color mixing in edgetype LED could be solved by using the ∧-shaped window color mixing bar.
