Description

  Embodiments described herein relate generally to a liquid crystal display panel.

  In recent years, a high-performance liquid crystal display device having high brightness and high definition has been demanded. In such a liquid crystal display device, for example, an active matrix type liquid crystal display panel is often used. The liquid crystal display panel includes an array substrate, a counter substrate, and a liquid crystal layer sandwiched between the array substrate and the counter substrate. The array substrate includes a plurality of scanning lines and a plurality of signal lines wired so as to cross each other, and a thin film transistor (Thin Film) as a switching element formed in each pixel region defined by the scanning lines and the signal lines. Transistor: TFT).

  The counter substrate includes a counter electrode and a color filter in which three kinds of colored layers of red, green, and blue, which are the three primary colors of light, are formed in a line shape. The array substrate and the counter substrate are bonded and bonded together by a sealing material disposed on the peripheral edge of both substrates. Polarizing plates are respectively disposed on the outer surface of the array substrate and the outer surface of the counter substrate.

  In the liquid crystal display panel, the color filter has a black matrix layer overlapping the signal lines and the scanning lines. The black matrix layer is formed so as to overlap between the two types of colored layers and the frame portion. Each colored layer and the black matrix layer have a structure in which the colored layer rides on the black matrix layer in order to prevent light leakage and color mixing due to patterning accuracy.

  The liquid crystal display panel includes a plurality of columnar spacers as a plurality of spacers for maintaining a constant gap between the array substrate and the counter substrate. When the columnar spacers are formed on the array substrate by photolithography, the columnar spacers can be arranged avoiding the display area, so that good display quality can be obtained. At this time, as for the region where the columnar spacer is arranged, in order to maintain the uniformity of the cell gap, a region that can ensure stable flatness is selected and arranged for both the array substrate and the counter substrate. Further, the columnar spacers are arranged in the vicinity of the intersections of the signal lines and the scanning lines so as not to overlap the openings and to avoid the periphery of the contact holes of the array substrate in order to ensure stable flatness.

  By arranging the columnar spacers on the black matrix layer, it has contributed to uniform cell gaps by selectively arranging the columnar spacers and improving the height accuracy.

  However, in recent years, development of a liquid crystal display panel in which a color filter in which four or more kinds of colored layers are combined in various ways has been advanced. In this case, the color filter has a contact portion of four or more colored layers. Due to variations in the patterning of the colored layers, the colored layers may overlap or have intervals in the contact portion.

  For this reason, the tolerance in the thickness direction of the color filter increases due to variations in the overlapping of the colored layers, so that it is difficult to maintain a uniform cell gap by the columnar spacers disposed opposite to the contact portions of the colored layers. The maintenance of the uniform cell gap becomes more difficult as the contact portion of the colored layer facing the columnar spacer is a contact portion of more kinds of colored layers.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a liquid crystal display panel excellent in display quality, which can keep a gap between an array substrate and a counter substrate constant.

The colored layers 50 </ b> R, 50 </ b> G, 50 </ b> B, and 50 </ b> W are formed so that the periphery is overlapped with the light shielding portion 51.

  The colored layers 50 </ b> R, 50 </ b> G, 50 </ b> B, and 50 </ b> W are arranged in an island shape with different types in a plurality of directions along the planes of the array substrate 1 and the counter substrate 2, and each form a pixel 13. The colored layers 50R, 50G, 50B, and 50W are formed in a rectangular shape having sides along the first direction X and the second direction Y, which are a plurality of directions. The colored layers 50R, 50G, 50B, and 50W are arranged so as to be shifted from each other in the second direction Y in the first direction X, and are arranged in a straight line in the second direction Y.

  The colored layers in one row are alternately arranged in the order of the colored layer 50R, the colored layer 50G, the colored layer 50B, and the colored layer 50W in the first direction X, and the colored layer in the next row is arranged in the first direction X. The colored layer 50B, the colored layer 50W, the colored layer 50R, and the colored layer 50G are alternately arranged in this order.

  As shown in FIG. 7 and FIG. 8, among the plurality of colored layers, the first colored layer 50R, the second colored layer 50B adjacent to the first colored layer 50R in the second direction Y, and the first colored layer 50R The third colored layer 50G adjacent to the first direction X and the fourth colored layer 50W adjacent to the second colored layer 50B in the first direction X and adjacent to the third colored layer 50G in the second direction Y are different from each other. (Color) is different. In this embodiment, the first colored layer 50R, the second colored layer 50B, the third colored layer 50G, and the fourth colored layer 50W form one picture element.

  The plurality of colored layers have at most n-1 types of colored layer contact portions. Here, the contact portion is a portion where n-1 types of colored layers may overlap at the maximum. In this embodiment, the colored layers 50R, 50G, 50B, and 50W have contact portions P of three types of colored layers at the maximum. The number of contact portions P between the corner portions of the plurality of colored layers is two. The contact part P is positioned so as to overlap the light shielding part 51. The columnar spacer 35 is overlapped with the light shielding portion 51 and the contact portion P.

  As shown in FIGS. 8 and 9, the first boundary line B1 between the first colored layer 50R and the second colored layer 50B and the second boundary line B2 between the third colored layer 50G and the fourth colored layer 50W Let the interval in the second direction Y be Δy. The width of the light shielding portion in the second direction Y is defined as By. The amount of deviation of the first boundary line B1 toward the second boundary line B2 in the second direction Y and the amount of deviation of the second boundary line B2 toward the first boundary line B1 are defined as Wcy1.

  In the second direction Y, the amount of shift of the first boundary line B1 toward the first side edge 51a of the light shielding part 51 facing the first boundary line B1, and the second of the light shielding part 51 facing the second boundary line B2. The shift amount of the second boundary line B2 toward the side edge 51b is defined as Wcy2.

  In the second direction Y, the amount of displacement of the first side edge 51a of the light shielding portion 51 toward the first boundary line B1 and the amount of displacement of the second side edge 51b of the light shielding portion 51 toward the second boundary line B2 are calculated. Let it be Wby. The shift amounts Wcy1, Wcy2, and Wby are assumed to be manufacturing errors.

Then, the following relational expression,
2Wcy1 <Δy <By
It satisfies.

  Next, the width of the columnar spacer 35 in the second direction Y is Sy. The overlapping width of each colored layer of 50R, 50G, 50B, and 50W and the light shielding part 51 in the second direction Y is defined as My. In addition, when the overlapping width of the colored layer and the light shielding portion 51 is large or small in one pixel, the small width is defined as My. A displacement amount of the columnar spacer 35 in the second direction Y toward the first side edge 51a side or the second side edge 51b side of the light shielding portion 51 is defined as Gy. The shift amount Gy assumes a misalignment that is an error when the array substrate 1 and the counter substrate 2 are aligned in the second direction Y.

Then, the following relational expression,
Sy ≦ By ≦ Sy + 2 (My + Gy)
It satisfies.

  For example, in the case of My = 4 μm and Gy = 3 μm, if By ≦ Sy + 14 μm, the columnar spacer 35 can always maintain a stable height while being shielded from light, and can prevent a decrease in aperture ratio.

  According to the liquid crystal display panel configured as described above, the liquid crystal display panel includes an array substrate 1, a counter substrate 2, a liquid crystal layer 3, a plurality of pixels 13, a color filter 50, and a plurality of columnar spacers 35. And. The color filter 50 includes a light shielding portion 51 and colored layers 50R, 50G, 50B, and 50W. The colored layers 50R, 50G, 50B, and 50W have a maximum of three types of colored layer contact portions P. The contact part P is positioned so as to overlap the light shielding part 51. The columnar spacer 35 is formed on the array substrate 1 and overlaps the light shielding portion 51 and the contact portion P to maintain a gap between the array substrate 1 and the counter substrate 2. In the above embodiment, 2Wcy1 <Δy <By is satisfied.

  The colored layers are repeatedly shifted for each line so as not to form contact portions of more than three types of colored layers. Variations in the height of the color filter 50 (the height of the colored layer riding on the light shielding portion 51) can be suppressed. Since the more stable height (thickness) accuracy of the abutting portion of the columnar spacer 35 can be obtained, the gap between the array substrate 1 and the counter substrate 2 can be held constant by the columnar spacer 35.

  High-brightness, high-definition liquid crystal display panel, that is, when a high aperture ratio is required, it is particularly effective under the condition of Sy ≦ By ≦ Sy + 2 (My + Gy), and a uniform cell even if the above deviation (variation) occurs in the process A gap can be maintained.

  As described above, a liquid crystal display panel excellent in display quality that can maintain a constant gap between the array substrate and the counter substrate can be obtained. In addition, a liquid crystal display panel with high luminance and high performance and high product yield can be obtained.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the components without departing from the scope of the invention in the implementation stage. Various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiments. For example, some components may be deleted from all the components shown in the embodiment.

  For example, as shown in FIG. 10, when the columnar spacers 35 are arranged opposite to the corners of the colored layers 50R, 50G, 50B, and 50W, the colored layer is subjected to a design in which the corners are removed, for example, R processing or C processing. Good. Even if a gap occurs between the colored layers, if the gap is smaller than the size of the columnar spacer 35, the height of the counter substrate 2 does not vary. Thereby, it can contribute to formation of a uniform cell gap.

  As shown in FIG. 11, the colored layers 50R, 50G, 50B, and 50W may be arranged in a straight line in the first direction X and may be arranged to be shifted from each other in the first direction X in the second direction Y. In this case, the above-described effects can be obtained.

The shape of the colored layers 50R, 50G, 50B, and 50W is not limited to a rectangular shape such as a rectangle and can be variously modified, and may be a triangle, a pentagon or more polygon.
As shown in FIG. 12, when the colored layers 50R, 50G, 50B, and 50W are hexagonal, the colored layer has a maximum of three types of colored layer contact portions P. Also in this case, the above-described effects can be obtained.

The type of the colored layer is not limited to the four types described above, but may be other four types or five or more types, and in this case, the above-described effects can be obtained.
The columnar spacers 35 need only be formed on the array substrate 1 or the counter substrate 2 as well as the array substrate 1, and thereby the above-described effects can be obtained.
