The present invention provides a transreflective type liquid crystal display unit, which can reduce power consumption of backlight and displays high-quality image. The liquid crystal display unit of the present invention comprises a first reflective electrode 105, which is installed on inner surface of one substrate 100 and has reflective surfaces on front and rear surfaces and is designed to have reflective lens structure with a convex portion to face to a counter electrode and has an opening 153 at the vertex of said convex portion. Further, the liquid crystal display unit has a second reflective film 104 having reflective surface on the surface facing to the first reflective electrode 105 between the first reflective electrode 105 and said one substrate 100 and under the opening 153 of the first reflective electrode 105. A light entering from the direction of said one substrate 100 is reflected by the rear surface of the first reflective electrode 105 and by the front surface of the second reflective film 104, and the light is converged to the opening 153 of the first reflective electrode 105 and is allowed to pass toward the other substrate 200.
