摘要： PROBLEM TO BE SOLVED: To provide a front light type liquid crystal display with which low- visibility in observing image is reduced and reflection loss accompanying use of a light guiding plate is eliminated. SOLUTION: Light emitted from LEDs (light emitting diodes) 31, 35 is introduced into light scattering transmission bodies 32, 36 and emitted from emission surfaces 34, 38 to an air space AR. Most of the emitted light is made obliquely incident on the inner side face 21 of a protective panel 20 directly or indirectly. A traveling direction of illumination light made obliquely incident on an illumination light direction adjusting surface 11 of a liquid crystal display panel 10 is adjusted to be close to a direction vertical to the liquid crystal display panel 10 by refraction in incidence or by the refraction in incidence and by internal reflection after incidence and subsequently the illumination light is made incident on the inside of the liquid crystal display panel 10 operating with a reflective mode and contributes to displaying. Fine prism lines, Fresnel lens shaped element lines, minute island shaped protrusion groups and so on are formed on the illumination light direction adjusting surface 11.
