PURPOSE:To obtain the reflection type color liquid crystal display device which provides a bright display without using any back light by forming a transparent fluorescent layer on a reflection electrode and converting ultraviolet light into visible light. CONSTITUTION:The reflection electrode 43 made of aluminum, silver, etc., is formed in an area corresponding to each picture element and serves as a picture element electrode, and its surface is covered with the fluorescent layer 44, made of transparent resin to which fluorescent pigment is added, including a gate bus electric conductor 32, a source bus electric conductor 39, and an ES layer 42. Incident light 20 is made incident from an opposite-side substrate 27 and reaches a TFT-side substrate 26. In this case, some of ultraviolet rays are absorbed by the fluorescent layer 44, the light which is not absorbed by the layer 44 is reflected by the electrode 43, and part of the ultraviolet light is absorbed by the layer 44. The ultraviolet light absorbed by the layer 33 at the time of the incidence and reflection is converted into the visible light, which is projected on a display surface together with reflected light 21 through liquid crystal 49, a color filter 46, a counter electrode 47, and a glass substrate 45. Consequently, the display is bright and the display contrast becomes excellent. |
