Description

  The present invention relates to a color filter substrate including a color filter, a liquid crystal display panel including a color filter, and a method for manufacturing a plurality of color filter substrates.

  In recent years, a liquid crystal display panel has been used as a monitor for displaying data including a lot of information such as a portable television and a computer. A liquid crystal display panel generally includes an array substrate, a counter substrate, a liquid crystal layer sandwiched between the two substrates, and a color filter formed on one of the array substrate and the counter substrate. The array substrate includes a substrate, a plurality of pixel portions provided in a matrix on the substrate, and a plurality of pixel portions that are provided on the substrate so as to surround these pixel portions and that extend in the first direction. The first wiring and a plurality of second wirings extending in a second direction orthogonal to the first direction.

  The color filter has a plurality of striped red colored layers, a plurality of striped green colored layers, and a plurality of striped blue colored layers. Each colored layer is formed so as to overlap a plurality of pixel portions arranged in the first direction.

  When manufacturing a vertical stripe COA (color filter on array) type liquid crystal display panel in which colored layers are formed in stripes as described above, a mother glass having a size larger than that of the array substrate is prepared, and a plurality of mother glass on the mother glass is prepared. An array pattern such as first wiring and second wiring, and a color filter are formed in the rectangular effective area. Subsequently, after a plurality of counter substrates are arranged to be opposed to the effective area and bonded together, the mother glass is divided along the periphery of the effective area. As described above, a plurality of empty liquid crystal display panels can be obtained by so-called multiple chamfering.

  When forming a color filter, first, for example, a red resist is applied on a mother glass by a spin coating method, and then a plurality of red colored layers are simultaneously formed in each effective region by patterning and baking.

  Subsequently, the same process is repeated to form a plurality of green colored layers and a plurality of blue colored layers. That is, when forming a plurality of green colored layers, a green resist is applied onto a mother glass on which a plurality of red colored layers are formed by a spin coating method, and then patterned and baked to each effective region. A plurality of green colored layers are formed simultaneously. In addition, when forming a plurality of blue colored layers, a blue resist is applied by spin coating on a mother glass on which a plurality of red and green colored layers are formed, followed by patterning and baking. A plurality of blue colored layers are simultaneously formed in the region.

By using the spin coating method as described above, the color filter is formed in each effective region with a red colored layer, a green colored layer, and a blue colored layer adjacent to each other (see, for example, Patent Document 1). .
Japanese Patent Laid-Open No. 5-224013

  In the resist coating process using the spin coat method, the second and subsequent color resists, which are the green resist applied to the second color and the blue resist applied to the third color, may not be applied to a uniform film thickness.

  First, the mother glass overlaps with the rotation axis of the mother glass in the coating process and is provided side by side in the extending direction of the diagonal line of the first area, and the effective area where the resist is dropped (hereinafter referred to as the first area). And a first pattern having an effective area (hereinafter referred to as a second area) and an effective area (hereinafter referred to as a third area) provided side by side in the first direction and the second direction. The case will be described.

  In this case, the resists for the second and subsequent colors are likely to spread in the first region and the third region, so that the resist is applied with a uniform film thickness in the first region and the third region. On the other hand, the resists for the second and subsequent colors are less likely to spread in the second region, but are liable to flow only in the direction along the extension of the diagonal line of the first region from the corner of the first region. Thereby, a recessed part may be formed in the surface of the resist of the 2nd color after the 2nd area | region which overlapped with the extended line of the diagonal line of a 1st area | region. In this case, the second and subsequent resists in the second region are not applied with a uniform film thickness. Since the concave portion is formed on the surface of the colored layer, the gap of the liquid crystal layer and the liquid crystal alignment are changed. As a result, the display quality is lowered in the recess.

  Next, the mother glass has an effective area (hereinafter referred to as a fourth area) provided so that a diagonal extension passes through the rotation axis of the mother glass in the coating process, and is opposite to the rotation axis with respect to the fourth area. Effective area (hereinafter referred to as the fifth area) provided on the side, and an effective area (hereinafter referred to as the sixth area) provided side by side in the first direction and the second direction with the fourth area. The case of the second pattern will be described.

  In this case, the resists for the second and subsequent colors are likely to spread in the fourth region and the sixth region, so that the resist is applied with a uniform film thickness in the fourth region and the sixth region. On the other hand, the resists for the second and subsequent colors are less likely to spread in the fifth region, but are liable to flow only in the direction along the extension of the diagonal line of the fourth region from the corner of the fourth region. Thereby, a recessed part may be formed in the surface of the resist of the 2nd color after the 5th area | region which overlapped with the extended line of the diagonal line of a 4th area | region. In this case, the second and subsequent resists in the fifth region are not applied with a uniform film thickness. Since the concave portion is formed on the surface of the colored layer, the display quality is deteriorated in the concave portion.

  Next, a lattice COA type liquid crystal display panel will be described together with a resist coating process using the first and second patterns of mother glass. In a lattice COA type liquid crystal display panel, a red colored layer formed in the first color is formed in a lattice shape. Here, the red colored layer formed in the first color overlaps the plurality of pixel portions arranged in the first direction and also overlaps the second wiring. For this reason, the red colored layer is formed so as to divide the green colored layer and the blue colored layer.

  When the mother glass has the first pattern, the resists for the second and subsequent colors are likely to spread in the first region and the third region, and are thus applied with a uniform film thickness in the first region and the third region. On the other hand, the resists for the second and subsequent colors are difficult to spread in the second region, but only in the direction along the extension line extending from the corner of the first region to the bisector of the first region outside the first region. It becomes easy to flow. As a result, a recess may be formed on the surface of the second and subsequent colors of the resist in the second region that overlaps the extended line that extends the bisector of the first region to the outside of the first region. In this case, the second and subsequent resists in the second region are not applied with a uniform film thickness. Since the concave portion is formed on the surface of the colored layer, the display quality is deteriorated in the concave portion.

  In addition, when the mother glass has the second pattern, the second and subsequent color resists are likely to spread in the fourth region and the sixth region, and therefore the uniform thickness is obtained in the fourth region and the sixth region. To be applied. On the other hand, the resists for the second and subsequent colors are difficult to spread in the fifth region, but only in the direction along the extension line extending from the corner of the fourth region to the bisector of the fourth region outside the fourth region. It becomes easy to flow. As a result, a recess may be formed on the surface of the resist for the second and subsequent colors in the fifth region that overlaps the extended line that extends the bisector of the fourth region to the outside of the fourth region. In this case, the second and subsequent resists in the fifth region are not applied with a uniform film thickness. Since the concave portion is formed on the surface of the colored layer, the display quality is deteriorated in the concave portion.

A red resist is applied on the entire mother glass 10 by a spin coating method that is performed by rotating 10. Thereafter, by similarly patterning, a plurality of colored layers 30R having contact holes 25 are formed in the first region R4, the second region R5, and the third region R6, respectively.

The plurality of colored layers 30R are formed with a uniform film thickness.

  Subsequently, an ultraviolet curable acrylic blue resist solution (hereinafter referred to as a blue resist) is applied to the dropping region R7 on the mother glass 10 on which the plurality of colored layers 30G, the plurality of divided portions 31 and the plurality of colored layers 30R are formed. The blue resist is applied to the entire surface of the mother glass 10 by a spin coating method in which the mother glass 10 is rotated. Thereafter, by similarly patterning, a plurality of colored layers 30B having contact holes 25 are formed in the first region R4, the second region R5, and the third region R6, respectively.

  Over the prepared mother glass 40, ITO is deposited by, for example, a sputtering method to form a conductive film. Thereafter, the plurality of counter electrodes 42 are formed so as to overlap the plurality of effective regions R3 by patterning the conductive film. Subsequently, after an alignment film material such as polyimide is applied to the entire mother glass 40, patterning is performed to form alignment films 43 in the plurality of effective regions R3. Thereafter, the alignment films 43 are subjected to alignment treatment (rubbing). As a result, nine counter substrates 2 are formed on the mother glass 40.
