Abstract: A color filter substrate is provided that includes a base plate, a resin layer disposed on the base plate, a reflective layer disposed on the resin layer and including a reflective portion and an transmissive portion, and a colored layer disposed on the reflective layer. An area of the resin layer corresponding to at least a portion of the transmissive portion is colored with the same color as the colored layer disposed in correspondence with the transmissive portion.

Abstract: A substrate is provided for an electro-optical device comprising a substrate, a base layer formed on the substrate and having a plurality of concave portions or convex portions on the surface thereof, and a reflecting layer formed on the base layer and having light reflecting property, wherein a plurality of concave portions or convex portions is formed so as not to extend to the edge of the base layer. According to this construction, a surface provided with concavo-convex portions is spaced apart from the edge of the base layer. Therefore, the sidewall surface that forms the edge is substantially flat. As a result, the base layer does not peel from the substrate when developing the photosensitive material which becomes the base layer.

Abstract: A photosensitive resin applied onto a substrate is exposed using a mask. In this exposure step, by appropriately setting the size of each light transmitting portion formed in the mask and an exposure gap, an exposure intensity profile on a surface of a photosensitive resin is formed so as to have an increasing and decreasing curve along the surface thereof. When the exposure is performed in accordance with the exposure intensity profile, followed by development, a resin layer having surface irregularities is formed. Subsequently, a reflection layer made of a metal thin film or the like is formed on this resin layer.

Abstract: A substrate is provided with a light reflecting film in which the depths of a plurality of concave portions formed on the surface of the base or the heights of a plurality of convex portions formed on the surface of the base are substantially equal, the planar shapes of the plurality of concave portions or the convex portions are overlapped circles and overlapped polygons, or any one of the aforesaid circles and polygons, and a plurality of concave portions or convex portions are randomly arranged over a plane, the substrate with the light reflecting film being prepared by using a mask comprising light-transmitting parts or non-light-transmitting parts formed by a plurality of dots less than the number of the dot regions as one unit, in which the light-transmitting parts or the non-light-transmitting parts are randomly arranged in the unit, and a plurality of the one unit is repeated.

Abstract: A substrate is provided with a light reflective film including a base and a reflective layer, in which a plurality of concave portions or convex portions formed on the surface of the base are randomly arranged in the plane direction in 100 to 2,000 RGB dot units or a whole screen unit, are formed using a mask in which light transmissive or non-transmissive portions are randomly arranged in the plane direction in 100 to 2,000 RGB dot units or the whole screen unit.

Abstract: A light reflecting film is formed such that a plurality of concave portions or convex portions formed on a base are aligned randomly over a plane by using a mask in which the positions of light-transmitting parts or non-light-transmitting parts are allocated according to a random function, and the light-transmitting parts or non-light-transmitting parts are aligned randomly over a plane.

Abstract: A substrate for an electrooptical device includes a base 1 in which a plurality of display dots D is formed, an underlayer 4 formed on the base 1, a reflective layer 2 formed on the underlayer 4, and color layers 3r, g, and b formed on the reflective layer 2. The underlayer 4 is provided at regions corresponding to the display dots D but is not provided at regions between the display dots D. In addition, concave areas are provided at the regions between the display dots D, and a light-shielding layer 3k is provided so as to get into the concave areas. Accordingly, the light-shielding layer 3k, and the color layers 3r, g, and b level with each other.

Abstract: A substrate is provided with a light reflection film in which the heights of a plurality of convex portions or the depths of concave portions formed on a base material are specified to be substantially the same. The two-dimensional shapes of the plurality of convex portions or concave portions are specified to be the two-dimensional shapes of independent circles and polygons, or of either of them. In addition, the plurality of convex portions or concave portions are arranged in the direction of the plane on a random basis. The substrate is formed using a mask in which light transmission portions or light non-transmission portions are formed in units of dots, the number thereof being smaller than the number of dot regions. The dots are arranged irregularly in each of the units, and a plurality of units are included.
