Description
Technical field
The invention relates to a kind of display device, and particularly relevant for a kind of thin-type display device.
Background technology
In recent years, traditional CRT display is replaced by thin-type display device gradually.Common thin-type display device comprises liquid crystal indicator, plasma display system, electrophoretic display apparatus and organic LED display device etc. at present, and wherein the popularity rate with liquid crystal indicator is the highest again.
Liquid crystal indicator comprises display panels and in order to the backlight module of display light source to be provided.Common display panels is a liquid crystal display panel of thin film transistor at present, and it comprises thin-film transistor array base-plate, colored optical filtering substrates and is disposed at liquid crystal layer therebetween.Recently develop and a kind of gate driver circuit is integrated in the technology of thin-film transistor array base-plate, promptly so-called gate on array (GOA) technology.The GOA technology is when making thin-film transistor array base-plate, produces gate driver circuit simultaneously.Gate driver circuit can be used for replacing grid drive chip, so can save production cost.
Fig. 1 is the partial cutaway schematic of the liquid crystal indicator of the existing a kind of GOA of application technology.Please refer to Fig. 1, available liquid crystal display device 100 comprises inside casing 110, housing 120, display panels 130 and backlight module 140.Inside casing 110 has the support portion 112 in order to support display panels 130, and backlight module 140 is disposed at display panels 130 belows.Housing 120 comprises the upright preceding frame 122 and back of the body frame 124 of group mutually, and housing 120 is in order to coat inside casing 110, display panels 130 and backlight module 140.Display panels 130 comprises thin-film transistor array base-plate 132, colored optical filtering substrates 134, frame glue 136 and liquid crystal layer 138.Frame glue 136 and liquid crystal layer 138 are disposed between thin-film transistor array base-plate 132 and the colored optical filtering substrates 134, and liquid crystal layer 138 is disposed in the zone that frame glue 136 crossed.
Hold above-mentionedly, thin-film transistor array base-plate 132 has the gate driver circuit 133 that goes out with the GOA fabrication techniques, and in order to protect gate driver circuit 133, liquid crystal layer 138 needs to extend to the edge of thin-film transistor array base-plate 132, with cover gate driving circuit 133.Correspondingly, frame glue 136 need move to more the position near the edge of thin-film transistor array base-plate 132.Yet the end 123 that is positioned at display panels 130 tops of frame 122 was to correspond to liquid crystal layer 138 but not frame glue 136 before this will cause.So, when current frame 122 was pushed by external force F1, preceding frame 122 will have influence on liquid crystal layer 138, caused liquid crystal indicator 100 to produce the ripples line when showing.
Fig. 2 is the partial cutaway schematic of the liquid crystal indicator of the existing another kind of GOA of application technology.Please refer to Fig. 2, in order to improve above-mentioned shortcoming, existing liquid crystal indicator 100 ' shortens the development length of the preceding frame 122 ' of housing 120 ', and the end 123 of frame 122 ' is shunk back to the edge of thin-film transistor array base-plate 132 before making.So, though can avoid the phenomenon of ripples line, can cause light leakage phenomena.
In more detail, because the light shield layer 135 of colored optical filtering substrates 134 can't extend to the edge when making, so have from the parasitic light 142 of the edge outgoing of display panels 130.Though preceding frame 122 ' can be used to block parasitic light 142, after the development length of former frame 122 ' shortened, the shading scope of preceding frame 122 ' also shortened thereupon.So parasitic light 142 passes liquid crystal indicator 100 ' easily, causes light leakage phenomena.
Summary of the invention
The invention provides a kind of display device, in case leak-stopping light and avoid housing to suffer oppression producing the ripples line.
For reaching above-mentioned advantage, the present invention proposes a kind of display device, and it comprises inside casing, display panel and housing.Inside casing has the support portion that extends internally, and display panel configurations is on the support portion, and display panel has two substrates and is arranged at frame glue between this two substrate.Housing coats inside casing and display panel, and housing has the fixed part that extends to the display panel top and from the terminal extended light shielding part of fixed part.Fixed part system contact display panel, and the end that connects the fixed part of light shielding part be positioned at display panel frame glue directly over.Light shielding part system extends to the top, zone that frame glue is crossed, and the segment distance of being separated by between light shielding part and the display panel.
In one embodiment of this invention, above-mentioned display panel is a display panels, and more comprises liquid crystal layer.Liquid crystal layer is disposed between above-mentioned two substrates and is positioned at the zone that frame glue is crossed, and the substrate that is positioned at below the frame glue is to have the active assembly array substrate that is integrated with driving circuit.Driving circuit system is positioned at the below, zone that frame glue is crossed, and the liquid crystal series of strata cover driving circuit.
