FIG. 8 is a sectional view for explaining a manufacturing process of the color liquid crystal display device 1. The light shielding member 4 is formed on the glass substrate 2 using a photo-etching technique as shown in FIG. On this, color filters 6R, 6G, 6B are formed in this order by, for example, screen printing.

[Problem to be Solved by the Invention] FIG. 9 is a diagram for explaining a problem of the conventional example. The color filters 6R, 6G, 6B formed on the glass substrate 2 are mutually laminated on the light shielding member 4 as described above. Such a situation occurs when the width L1 of the display area 5 is 100, for example.
It becomes remarkable in a minute case such as about μm or less. That is, the above-described printing method has a problem that it is impossible to control the shape and dimensions with high accuracy. In addition, since the end portions of the color filters 6R, 6G, and 6B are laminated, the surface of the coating layer 7 is not flat, and the display electrode 8 formed thereon is not flat. This causes problems such as an electric resistance value exceeding a predetermined value or disconnection.

[Effects of the Invention] As described above, according to the present invention, a colored member formed for each display picture element region is formed by a technique such as printing or the like, in which it is difficult to control the shape and dimensions of the colored member with high precision. Therefore, even if the end portions of the coloring members are laminated, the laminated portion can be removed, and the coloring member on the display picture element region can be made flat. Accordingly, even when the display electrode is formed over the coloring member between the plurality of coloring members, an undesired state such as disconnection of the display electrode can be prevented.

Also, as described above, a positive type photosensitive resin is applied to the colored member side of the substrate where the light shielding member and the colored member mounted on the display picture element region are formed on the substrate, and the substrate is cured. The photosensitive resin on the display picture element area is solubilized and removed by irradiating light from the side and using the light shielding member as a mask. Thereby, the recess surrounded by the adjacent coloring member and light-shielding member can be filled with the positive photosensitive resin, and when the display electrode is formed thereon, it can be formed flat. Unwanted situations such as disconnection as described in the section can be prevented.

Further, according to the present invention, when filling the recess, a negative photosensitive resin is applied to the colored member side of the substrate on which the light shielding member and the colored member attached to the display picture element region are formed, Light is irradiated from the side opposite to the light blocking member to cure the photosensitive resin on the coloring member. At this time, the photosensitive resin on the light shielding member is not cured and is removed. A filling layer is formed over the entire surface of the light shielding member and the negative photosensitive resin, and the photosensitive resin on the coloring member is removed together with the filling layer. Thus, the recess surrounded by the adjacent coloring member and light-shielding member can be filled with the filling layer, and the preferable effects as described above can be obtained.

Further, according to the present invention, the inner surface of the coloring member mounted on the display pixel region and the inside of the filling layer formed on the light blocking member constituting the non-display pixel region are formed flat, and the upper surface thereof is formed. Since the smoothing layer, the display electrode, and the alignment film are sequentially laminated,
The coloring members do not overlap, and the display electrodes are formed flat, so that the increase in the resistance of the display electrodes, disconnection, and unclear color of the display image as described in the related art can be prevented.
