PURPOSE: A method for manufacturing a light guiding plate is provided to shorten time required for manufacturing processes by printing a solution capable of dissolving a light guiding main body and violating a part of the solution. CONSTITUTION: A first solution is printed on a light guiding panel(101) according to patterns using a silk screen printing method. The first solution is dissolves the light guiding panel. A part of the first solution is volatilized after a pre-set period of time and remained part of the first solution is dried. A second solution is printed on the light guiding panel according to patterns using the silk screen printing method. The second solution is dissolves the light guiding panel. A part of the second solution is volatilized after a pre-set period of time and remained part of the second solution is dried. The first solution is methylene chloride, and the second solution is chloroform.
