Abstract
PURPOSE: To optimize the contrast ratio of the liquid crystal display element consisting of the liquid crystal cell of twisted nematic structure, one sheet of polarizing plate and one sheet of reflecting plate by providing a multiplity of dot-form nonconductive portions to the display pattern of a transparent conductive film.
CONSTITUTION: A transparent conductive film 12 corresponding to the pattern 11 to be displayed is formed on the surface of a transparent substrate in contact with the liquid crystal layer and the circular non-conductive portions 13 are provided at a diameter 200μ or under and in the positions mutually opposing to the vertex of triangles in such a manner that the area ratios of the portions 13 to the pattern 11 become 30 to 70%, preferably 50%. Then, when an electric field is applied between the transparent electrodes and the liqiid crystal layer between the electrodes has lost the twisted structure, the quantity of the light which passes through the twisted liquid crystal layer at the incident time and passes the liquid crystal layer having lost the twisted structure after the reflection increases and the quantity of the light which passes through the liquid crystal layer having lost the twisted structure both at the incident time and after the refection decreases.
