Background technology
LCD is a flat-panel monitor commonly used at present, and wherein Thin Film Transistor-LCD (ThinFilm Transistor Liquid Crystal Display is called for short TFT-LCD) is the main product in the LCD.
Panel of LCD comprises color membrane substrates (Color Filter is called for short CF) and array base palte, clips one deck liquid crystal between color membrane substrates and the array base palte.Be formed with envelope frame glue in the neighboring area of color membrane substrates and array base palte, make color membrane substrates and array base palte box.The composition of envelope frame glue mainly is an epoxy resin, and this composition needs the curing of ultraviolet ray (Ultraviolet Rays is called for short UV) irradiation and heating twice program to handle can reach the requirement of panel of LCD for envelope frame glue.Wherein, ultraviolet irradiation can be chosen in the color membrane substrates side or the array base palte side is carried out.
Yet, require the envelope frame glue zone of panel of LCD periphery more and more littler along with market is more and more higher for the lightening demand of LCD.For color membrane substrates, in order to prevent light leak, its neighboring area need be covered with black matrix (Black Matrix is called for short BM) substantially, and the material of black matrix is lighttight, so can only select to carry out from the array base palte side to the ultraviolet ray irradiation of envelope frame glue.
For array base palte, metal level as the part of circuit on it, in order to guarantee the resistor satisfied electricity requirement of array base palte periphery wiring, can require the resistance of its metal level the smaller the better, and this resistance reduces along with the increase of metal level area, therefore, the generalized case lower metal layer can be covered with the neighboring area of array base palte.
In order to satisfy the demand of envelope frame glue ultraviolet ray irradiation, as shown in Figure 1, prior art can be carried out metal hollow out to a certain degree, so that ultraviolet passing through.
Yet, because ultraviolet ray is shone envelope frame glue in the hollow out zone that the array base palte side can only see through on the metal, can't not accept enough irradiations in the zone of hollow out corresponding to metal on the feasible envelope frame glue, make the state of cure of envelope frame glue weaken.If the black matrix of color membrane substrates can be reflective, can also make those also be received ultraviolet irradiation by repeatedly reflecting by the position that metal level blocks, but the black matrix material of color membrane substrates is opaque substantially resin material, the insufficient problem that directly causes of this irradiation is exactly before the adhesive curing of envelope frame, envelope frame glue penetrates in the middle of the liquid crystal near the uncured one-tenth branch of a side (being designated hereinafter simply as the inboard of envelope frame glue) of liquid crystal, liquid crystal is polluted, thereby cause the quality problems of liquid crystal.

LCD (Liquid Crystal Display) array substrate that the utility model provides and panel of LCD, by increasing the area in the hollow out zone at close array base palte center on the metal level, reduce the area in the hollow out zone at close array base palte edge on the metal level, and the area in the hollow out zone at the hollow out at close array base palte center zone and close array base palte edge is smaller or equal to predefined value, overcome owing to metal level exists the envelope frame glue that causes near the inadequate problem of liquid crystal region ultraviolet curing, improved the inboard ultraviolet curing degree of envelope frame glue, reduced of the pollution of envelope frame glue for liquid crystal, but also can keep sealing cohesive strength between frame glue and the substrate substantially, do not influence envelope frame effect.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model embodiment clearer, below in conjunction with the accompanying drawing among the utility model embodiment, technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment one
Fig. 2 is the structural representation of the utility model LCD (Liquid Crystal Display) array substrate embodiment one, as shown in Figure 2, the neighboring area of this LCD (Liquid Crystal Display) array substrate 1 is laid with metal level 2, be formed with the hollow out zone on the metal level 2, the hollow out zone comprises a plurality of hollow-out unit 3, the area of each hollow-out unit 3 close array base palte 1 marginal portion is less than its area near array base palte 1 core, and the area in hollow out zone is smaller or equal to predefined value.
Wherein, the metal level of laying on the array base palte 12 is designed to the area of the hollow out region area at close array base palte 1 edge less than the hollow out zone at close array base palte 1 center, when making ultraviolet ray irradiation array base palte 1, envelope frame glue near array base palte 1 center can receive more ultraviolet ray irradiation, thereby improved the ultraviolet curing degree of the envelope frame glue at close array base palte 1 center, reduced to seal frame glue because of solidifying the pollution that not exclusively causes to liquid crystal; Simultaneously, the area in the hollow out zone on the metal level 2 is smaller or equal to predefined value, it is the area requirements that the area of metal on the metal level 2 reaches regulation, thereby guaranteed the resistance requirement of array base palte 1 peripheral cloth line resistance, can also guarantee to seal the cohesive strength between frame glue and the array base palte 1, not influence the effect of envelope frame.
When ultraviolet ray when array base palte 1 one sides are shone, ultraviolet ray shines on the envelope frame glue by a plurality of hollow-out unit 3 on the metal level 2, because the fretwork area of close array base palte 1 center on the metal level 2 (also promptly near liquid crystal) is greater than the fretwork area near array base palte 1 edge (also promptly away from liquid crystal), so the inboard state of cure at envelope frame glue is improved, because the possibility that liquid crystal is polluted away from the envelope frame glue of liquid crystal is significantly less than the envelope frame glue near liquid crystal, so reduce can not influence performance to ultraviolet ray irradiation away from the envelope frame glue of liquid crystal.
Wherein, each hollow-out unit 3 can comprise first figure and second graph, and first figure is near the edge of array base palte 1, and second graph is near the center of array base palte 1, and first area of graph is less than the area of second graph.Preferably possesses following proportionate relationship between the area of first area of graph and second graph: 0.2~1.Both can be independently of one another between first figure and the second graph, also can communicate with each other.
