Abstract
The present invention relates to a structure of a coloured filter on a liquid crystal display panel, which comprises a main body. The main body comprises four cut surfaces which present non-right-angle shapes and are respectively formed on four end points of the main body. The main body additionally has two notches which are respectively formed on two opposite lateral sides of the main body. When coloured filters form a triangular array, the cut surfaces and the notches can reduce the overlapping regions of the coloured filter and the other two adjacent coloured filters, so that the liquid crystal display panel has the advantages of light leakage prevention, high chromaticity and high contrast.

See also Fig. 2, it is the cross-sectional view according to another display panels of prior art drafting, in order to reduce the manufacturing process cost, the manufacturing process of deriving afterwards only forms color filter 23 on subtend substrate 22, do not form shading region in addition and have, its with the overlapping region 24 of color filter 23 as shading region.Yet, see also Fig. 3 A and Fig. 3 B, it shows that respectively prior art forms the color filter vertical view of rounded projections arranged (delta arrangement) and the cross-sectional view of Fig. 3 a-quadrant 34, for the color filter 3 that forms rounded projections arranged, red colored filter 31, green tint colo(u)r filter 32 and blue color colo(u)r filter 33 can cause three layers overlapping in zone 34, three layers of overlapping effect of colored filter make in this overlapping region 34 to produce juts 341, when liquid crystal display panel of thin film transistor is applied voltage, these jut 341 formed electric field intensity are regional strong than all the other, cause turn to degree and all the other regional liquid crystal molecules 39 of near the liquid crystal molecule 38 in this overlapping region that difference is arranged, and this jut 341 makes that also near cell gap (cell gap) d the overlapping region 34 is different with all the other zones, make display panels produce the light leak problem, not only chromaticity is bad, and causes contrast to descend.
Summary of the invention
At above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of colored filter that is applied on the display panels, it can make display panels avoid the light leak problem, improves chromaticity and improve contrast.
For achieving the above object, the invention provides a kind of colored filter that is used on the display panels, it comprises a body, body comprises that four cut face, this cuts face is on-right angle shape and four end points that are formed at body respectively, body has two breach in addition, this breach is formed at respectively on the limit, two opposite sides of body, during by this colored filter in the formation rounded projections arranged, this cuts face and this breach can reduce the overlapping region of this colored filter and other two adjacent colored filters, thereby makes display panels be avoided the light leak problem, improve chromaticity and improve contrast.
The above-mentioned face that cuts can be an inclined-plane or an arc surface.
Above-mentioned breach is formed on the mid point of side of body, and its shape can be rectangle, triangle, trapezoidal or arch.

Embodiment
See also Fig. 4 A, it is the colored filter first embodiment vertical view of the present invention.The colored filter that the present invention forms comprises a body 4, body comprises that four cut face 41, it is on-right angle shape (for example being an inclined-plane) and four end points that are formed at body respectively, and body has two breach 42 in addition, and it is rectangle and is formed at respectively on the limit, two opposite sides 43 of body.
The face that cuts forms one in the end points of body and cuts the portion 44 that cuts, embodiment preferably, and the length x that cuts the portion of cutting is 0＜x≤10 μ m, the width y that cuts the portion of cutting is 0＜y≤10 μ m.In addition, embodiment preferably, the length z of breach is 0＜z≤10 μ m, the width u of breach is 0＜u≤10 μ m.
With the structure of rounded projections arranged that prior art is formed, the present invention is according to the design of thin-film transistor array base-plate and breach is formed at two relative minor faces of body, and is positioned on the mid point of minor face.Yet, if the design difference of thin-film transistor array base-plate also can make breach be formed at two long relatively limits of body, and be positioned on the mid point on long limit.
See also Fig. 4 B, it forms the color filter vertical view of rounded projections arranged for the present invention, for the color filter 5 that forms rounded projections arranged, can avoid red colored filter 51, green tint colo(u)r filter 52 and blue color colo(u)r filter 53 to cause three layers overlapping in zone 54.Even when making color filter 5, cause red colored filter 51, green tint colo(u)r filter 52 and blue color colo(u)r filter 53 to cause three layers overlapping in zone 54 because of photolithographic fabrication flow process deviation of the alignment, still can significantly reduce the overlapping region, therefore, according to the present invention, can make display panels avoid the light leak problem, improve chromaticity and improve contrast.
According to the present invention, the face of cutting is arc surface 61 (shown in Fig. 5 A), or breach be shaped as triangle 72, trapezoidal 82 or arch 92 (shown in Fig. 5 B～5D), or other can avoid the overlapping design of colored filter, can make display panels avoid the light leak problem, improves chromaticity and improve contrast.
As be familiar with this technical field personnel understood, the above is embodiments of the invention only, be not in order to limit claim of the present invention; All other do not break away from the equivalence of being finished under the disclosed design and changes or modification, all should be included in the following claim.
