State the lower face that black ink layer 6 extends to the cover board 3.In this way, coating 6 energy of black ink layer after black ink layer 6
Enough it effectively prevent the optics that back light unit 1 is sent out to be overflowed from the lateral edges of back light unit 1 or display panel 2, and black ink
6 thickness of layer are small, are conducive to the narrow frame design of liquid crystal display die set.Further, which further includes bottom frame 7,
The side wall of the bottom frame 7 extends to the lower face of the cover board 3, and pastes and connect with the cover board 3.Preferably, the bottom frame 7
Sidewall upper to form consistent with 3 edge of cover board arc excessive.In this way, bottom frame 7 can be effectively played to back light unit 1
With the support protective effect of display panel 2, meanwhile, the side wall of bottom frame 7 extend to the lower face of the cover board 3 and with the cover board
3 paste connection, and realization is fixed and supported with cover board 7, and the liquid crystal display die set being arranged in this way is simple in structure in assembly, is not required to
Front frame is set, so as to effectively save consumptive material and assembly time, reduces production cost, improves working efficiency.In the present embodiment
In, the cover board 3 can preferably be equipped with touch control electrode layer towards the display panel side, be touched so that cover board 3 has
Control function is touched, the functional diversity of liquid crystal display device is increased.
Embodiment two
The present embodiment and previous embodiment structure type, principle is identical, differs only in, and the black matrix area 222 exists
It is equipped with opening corresponding to the boundary line viewing area AA and non-display area NA of the display panel and fills shading insulating layer 8.This
Sample, can make it is corresponding with the display panel edges non-display area NA in black matrix 222, black matrix 222 be located at it is non-display
The part in area and the part disconnection positioned at viewing area, ensure the pressure difference or black matrix of black matrix and pixel electrode when dark-state display
Smaller with the pressure difference of public electrode, greening bad phenomenon when to overcome dark-state to show improves display effect, and is filled with screening
It can more preferably ensure the stickup fixed function of sealant 23 and color membrane substrates 22 and array substrate 21 after light insulating layer 8.
The embodiment of the utility model above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously
Cannot it therefore be interpreted as the limitation to the utility model patent range, as long as using the form institute of equivalent substitution or equivalent transformation
The technical solution of acquisition, shall fall within the scope of the present invention.
