  As a method for forming a color filter pattern using the colored photosensitive resin composition of the present invention, for example, the colored photosensitive resin composition of the present invention is applied to a substrate or another resin layer (for example, on a substrate). And a colored layer is formed by removing volatile components such as a solvent, and exposing the colored layer through a photomask and developing the layer. (That is, a photolithographic method), a method using an inkjet device that does not require a photolithographic method, and the like. In the above photolithographic method, the coating film of the present invention can be obtained by not using a photomask and / or not developing during exposure.

Specifically, a plurality of TFTs 22 are formed for each pixel on the glass substrate 21 by a known method such as a photolithography technique (see FIG. 1). The TFT 22 is formed of, for example, molybdenum (Mo) on the glass substrate 21 and constitutes part of the gate line, and, for example, a nitride film (SiN _x ) and an oxide film formed on the gate electrode 22a. A gate insulating film 22b made of a laminated film of (SiO ₂ ), a polycrystalline silicon film 22c formed on the gate insulating film 22b, and a laminated film of an oxide film (SiO ₂ ) and a nitride film (SiN _X ), for example. The protective film 22d is formed of a film. A region facing the gate electrode 22a of the polycrystalline silicon film 22c is a channel region of the TFT 22, and regions on both sides of the channel region are a source region or a drain region. The source region of the polycrystalline silicon film 22c is electrically connected to a signal line 27 made of, for example, aluminum (Al) through a connection hole (contact hole) provided in the protective film 22d. The drain region of the polycrystalline silicon film 22c is electrically connected to the pixel electrode 24 through a connection hole (contact hole) 201 as will be described later.

  When forming a plurality of TFTs 22 on the glass substrate 21 for each pixel, an alignment mark (not shown) is formed on the glass substrate 21 simultaneously with the TFTs 22. As will be described later, this alignment mark serves as a reference for alignment in the formation process of the color filter layer 23. These alignment marks can also be used as marks serving as a reference for bonding the drive substrate and the counter substrate. The alignment mark can be formed in the same process using at least one layer when forming a metal layer such as wiring or a polycrystalline silicon layer in the manufacturing process of the TFT 22.

  Next, a colored photosensitive resin composition layer 23A having a film thickness of 0.5 to 5.0 μm, for example, 1.0 μm, is formed on the glass substrate 21 on which the TFT 22 and the alignment mark are formed by spin coating or other methods. To do. This colored photosensitive resin composition layer 23A corresponds to the color filter of the present invention.

  Subsequently, the colored photosensitive resin composition layer 23 </ b> A is dried by performing heat treatment at a temperature in the range of 30 to 120 ° C., preferably 60 to 110 ° C. In order to dry the colored photosensitive composition layer 23A, vacuum drying may be performed in combination with heat drying. Next, the colored photosensitive resin composition layer 23A is irradiated with ultraviolet rays through a photomask (not shown), and unnecessary portions (unexposed portions) are selectively removed with a developing solution, so that After forming a connection hole (contact hole) 201 reaching the drain region of the crystalline silicon film 22c, it is washed with water. Thereafter, in order to reflow (reflow) the colored photosensitive resin composition layer 23A and to cure the curable component contained in the colored photosensitive composition layer 23A, a temperature in the range of 100 to 300 ° C., for example, 150 Heat at ~ 230 ° C.

  Thereby, the colored photosensitive resin composition layer 23A becomes the color filter layer 23 including the red filter 23a, the green filter 23b, and the blue filter 23c corresponding to each pixel column (see FIG. 2). A region between the filters of the color filter layer 23 is a mixed region of adjacent colors. Since this region is a light-shielding region facing the signal line 27, there is no particular problem in quality. Note that the region between the filters may not be colored.

  Subsequently, a photosensitive resin film 29 as a protective film having a film thickness of 0.3 to 2.0 μm, for example, is formed so as to cover the color filter layer 23 by, for example, a spin coating method. Next, the photosensitive resin film 29 is irradiated with ultraviolet rays through a photomask (not shown), and the regions corresponding to the connection holes 201 and unnecessary portions are selectively removed with a developer, thereby polycrystal After a connection hole (contact hole) 202 reaching the drain region of the silicon film 22c is formed, it is washed with water. Thereafter, in order to reflow (reflow) the photosensitive resin film 29, heating is performed at a temperature in the range of 100 to 300 ° C., for example, 200 ° C. Next, in order to remove residues such as dyes and organic substances deposited in the contact hole 202, etching with oxygen plasma is performed, and further, for example, etching with dilute hydrofluoric acid is performed to remove the oxide film formed by oxygen plasma. To do.

  Next, a transparent conductive material, for example, ITO (Indium-Tin Oxide) is formed on the photosensitive resin film 29 by sputtering, for example, and this ITO film is formed by photolithography and etching. Patterning is performed to form a transparent pixel electrode 24 (see FIG. 3). The pixel electrode 24 may be formed of a metal such as aluminum (Al) or silver (Ag) depending on a device to be manufactured. After that, after forming an alignment film by a known method, a liquid crystal display device can be manufactured by bonding the drive substrate and the counter substrate.

  According to the colored photosensitive resin composition of this invention, it becomes possible to obtain the coating film, pattern, and color filter excellent in heat resistance.
