Abstract

The present invention can obtain a reflective layer with good light scattering effect by means of a simple manufacturing process. The exposure mask 7 a of the present invention is used in an exposure process for making the processed region 511 of the film body 51 a rough surface. This exposure mask 7 a has a first region 71 and a second region 72 . Among them, the first region 71 is used as a light-transmitting portion 81 that transmits light directed toward the periphery of the region to be processed 511 . On the other hand, while the second region 72 includes a plurality of dot regions 721 in which the light shielding portions 84 for shielding the light incident on the region 511 to be processed are respectively provided, the region other than the dot region 721 is provided so as to be lower than the light transmitting portion 81. The light transmittance of the semi-transmissive portion 86 transmits the light incident on the region 511 to be processed.

Description

technical field [0001] The present invention relates to a technique for scattering reflected light by roughening the surface of a reflective layer. Background technique [0002] In a so-called reflective liquid crystal display device, a reflective layer having light reflectivity is formed on a surface of a substrate holding liquid crystal. Then, external light such as sunlight and indoor lighting incident from the observation side is reflected by the surface of the reflective layer, and the reflected light is used for image display. In this configuration, when the surface of the reflective layer is completely flat, the light incident on the liquid crystal display device is reflected by the surface of the reflective layer and can be recognized by the observer. In this case, there is a problem that it is difficult to observe the display because images of persons and objects facing the display surface of the liquid crystal display device can be viewed in addition to the origin...

Problems solved by technology

However, when this method is used, since a flat surface reflecting the plate surface of the substrate exposed between the resin sheets and the flat surface of the top of each resin sheet appears on the surface of the reflective layer, light scattering cannot be sufficiently obtained. The problem of the effect (hereinafter referred to as "light scattering effect")
