Problems solved by technology

[0010] In this way, when a light-shielding layer is provided between display dots, conventionally, the thickness of the portion where the light-shielding layer is provided is increased, so that the variation in the cell gap increases, so there are problems such as that the rubbing process cannot be performed well on the alignment film.
In a liquid crystal device, an alignment film or a cover layer is usually formed on top of a light-shielding layer, and these layers make the surface of the substrate flat to some extent, but even so, the above-mentioned variation in the cell gap cannot be eliminated.

Abstract

In the substrate structure of liquid display device, roughness is depressed on the surface of plural pixels for display and areas between the pixels. Furthermore, it assures the planarity between a light shielding layer and a layer, for example a coloring layer, enclosed by the layer. To solve the problem, there is formed a substrate for photoelectric device, which includes a base 1 having a plurality of display pixels D, a base layer 4 formed on the base 1, a reflective layer 2 formed on the base layer 4, and coloring layers 3r, g, b formed on the reflective layer 2. The base layer 4 is arranged on an area corresponding to the display pixels D, instead of the areas between the display pixels D. A recess is formed on the area between the display pixels D. Because the light shielding layer 3k is involved in the recess, the light shielding layer 3k and the coloring layers 3r, g, b become flat.

Description

technical field [0001] The present invention relates to a substrate used in an electro-optical device such as a liquid crystal device, a method for manufacturing the substrate, an electro-optical device configured using the substrate, and an electronic device using the electro-optical device. Background technique [0002] In recent years, electro-optical devices have been widely used in electronic devices such as mobile phones and portable computers. As one of the electro-optic devices, there is known a transflective liquid crystal device capable of reflective display and transmissive display. [0003] When a reflective display is performed in this liquid crystal device, external light such as natural light or indoor light enters the liquid crystal device, and the light is reflected by a reflective layer provided inside the liquid crystal device, and the reflected light is emitted to the outside again. to display. At this time, in order to realize the function of the trans...
