Abstract: A method of fabricating a substrate for a display device prevents the problems occurring in the pattering process of a photosensitive organic material layer, such as the nullstage image transfernull and nullmask image reflectionnull. A photosensitive organic material layer is formed on or over a transparent plate, the layer being divided into a display section and a terminal section located outside the display section. The photosensitive organic material layer has a first thickness in the display section and a second thickness different from the first thickness in the terminal section. The layer is exposed to exposing light in such a way that the layer in the display section is exposed at a first exposure value according to the first thickness and the layer in the terminal section is exposed at a second exposure value according to the second thickness.

Abstract: A reflection-type liquid crystal display according to the invention includes two glass substrates, a transparent electrode provided on one glass substrate, an insulator film which is provided on another glass substrate and on which an uneven structure is formed, a reflecting electrode provided on the insulator film, and a liquid crystal layer sandwiched between a side of the transparent electrode and a side of the reflecting electrode. The insulator film includes a first insulating layer in which a large number of depressions isolated as surrounded by protrusions are irregularly arranged and a second insulating layer covering the insulating layer entirely. The protrusions are all connected in a network, so that if some of these protrusions have weaker adherence with an underlying layer, they can be supported by the surrounding protrusions.

Abstract: A reflector for a reflection-type LCD device is provided, which reflects efficiently incident light to the viewer's side and that suppresses the change of color tone. The reflector comprises a roughened surface having a protrusion pattern. The protrusion pattern gives inclination angle to the surface according to a specific distribution where a first component with an inclination angle value of 0null is 15% or less in area and a second component with an inclination angle value from 2null to 10null is 50% or greater in area. The protrusion pattern gives a variation range of chromaticity coordinates (x, y) on a chromaticity diagram dependent on an angle of view. The variation range is limited in a circle on the chromaticity diagram. The circle has a radius of approximately 0.05 and a center at a point corresponding to white color.

Abstract: In a reflection type liquid crystal display device having a front light and a reflection type liquid crystal panel including a reflection electrode of uneven structure, average tilt angles of the uneven structure of the reflection electrode are changed to form a high directivity reflective region having a characteristic reflecting an incident light from the front light in a vertical direction and a wide viewing angle reflective region having a characteristic reflecting an outside light incident slantingly from the front in a vertical direction, thereby forming the high directivity reflective region and the wide viewing angle reflective region to be mixed in the reflection electrode in the same display device.
