Below by the details with multiple embodiments of the open present invention of accompanying drawing, as clearly stated, in many practices
Will be explained in the following description.It should be appreciated, however, that the details in these practices is not applied to limit the present invention.Also
It is to say, in some embodiments of the present invention, the details in these practices is non-essential.Additionally, for the sake of simplifying accompanying drawing, one
A bit usual structure and assembly in the accompanying drawings by the way of simple signal for it.
Figure 1A to Fig. 1 E cuing open in multiple stages of manufacture method that be liquid crystal panel according to one of present invention embodiment
Face schematic diagram.The multiple stages manufacturing liquid crystal panel (or referred to as display floater) described further below.First, by mixture 100
Between injection first substrate 200 and relative second substrate 300.Here, mixture 100 can pass through mixed liquid crystal orientation chemical combination
Thing 110 is formed with multiple liquid crystal molecules 120.Wherein, mixture 100 can be described as liquid crystal compound or liquid crystal layer.
Liquid crystal molecule 120 can be various suitable liquid crystal molecule, for example: Wherein liquid crystal molecule 120 has one
Major axis bearing of trend N0.
LCD alignment compound 110 can have carbon-chain structure X, functional group A and first crosslinked functional group's (not illustrating),
Wherein carbon-chain structure X can affect the sensing of liquid crystal molecule 120, and the first crosslinked functional group can be under proper condition with another first
Crosslinked functional group's crosslinking (cross-link).LCD alignment compound 110 is a chemical molecular, and its molecular formula will be implemented below
Example elaborates.
Here, the functional group A of LCD alignment compound 110 can be to the inner surface 202 of first substrate 200 in mixture 100
Or the inner surface 302 of second substrate 300 provides absorption affinity so that LCD alignment compound 110 can adsorb in first substrate 200
Inner surface 202 and second substrate 300 inner surface 302, then functional group A can be described as adsorbing functional group A.However, in part feelings
Under condition, still there are the unadsorbed inner surface 202 in first substrate 200 of LCD alignment compound 110 and the second substrate 300 of part
Inner surface 302, the orientation power suffered by liquid crystal molecule 120 that is likely to result in is not enough or makes because LCD alignment compound 110 remains
The ghost (image sticking) becoming.
In multiple embodiments of the present invention, with reference to Figure 1B, alternative pass through external energy E1, such as illumination methods,
Mode of heating or combinations of the above make LCD alignment compound 110 energy absorption.Consequently, it is possible to most LCD alignment chemical combination
On the inner surface 302 with second substrate 300 for the adsorbable inner surface 202 in first substrate 200 of functional group A of thing 110, whereby,
The LCD alignment compound 110 positioned at first substrate 200 and the central authorities of second substrate 300 can be reduced, right the present embodiment is not
As limit.
In other parts embodiment, the absorption affinity of functional group A itself may be sufficiently high, and can make most liquid
Brilliant orientation compound 110 is adsorbed in the inner surface 202 of first substrate 200 and the inner surface 302 of second substrate 300.At this point it is possible to
Omit this step by external energy increase absorption affinity.
Come again, reference picture 1C, apply external voltage V on liquid crystal molecule 120 so that the interior table of neighbouring first substrate 200
Face 202 has a tilt angle T (pre-tilt angle) with the liquid crystal molecule 120 of the inner surface 302 of second substrate 300, or claims
Inclination angle.For example, in the present embodiment, external voltage V puts on the first conduction on the inner surface 202 of first substrate 200
The second conductive layer (mark) on layer (or referred to as pixel electrode, do not mark) and second substrate 300 inner surface 302, so that
The liquid crystal molecule 120 of the first conductive layer in adjacent inner surface 202 and the second conductive layer on inner surface 302 can have pre-dumping
Angle.
Here, alleged " liquid crystal molecule has a tilt angle " refers to the long axis direction N of liquid crystal molecule0And it is non-fully vertical
Or parallel to the inner surface 202 of first substrate 200 and the inner surface 302 of second substrate 300, the major axis extension side of this liquid crystal molecule
To N0It is referred to as tilt angle T with the angle of the inner surface of substrate, the scope of wherein tilt angle T is more than 0 degree and to be less than 90 degree.Change
Yan Zhi, can allow liquid crystal molecule 120 when being not powered on pressure, and liquid crystal molecule 120 is still in the inner surface 202 and the of first substrate 200
It is tilt angle T that the inner surface 302 of two substrates 300 has angle.Relatively, " liquid crystal molecule does not have tilt angle " refers to that liquid crystal divides
The major axis bearing of trend of son is completely perpendicular or parallel to the inner surface 202 of first substrate 200 and the inner surface of second substrate 300
302.In other words, liquid crystal molecule 120 can be allowed when being not powered on pressure, liquid crystal molecule 120 is still perpendicular or parallel to first substrate 200
Inner surface 202 and second substrate 300 inner surface 302.
Here, discussing applied voltage for the liquid crystal molecule 120 positioned at mixture 100 central authorities and adjacent inner surface respectively
202 impacts being constituted with the liquid crystal molecule 120 of inner surface 302.Liquid crystal molecule 120 positioned at mixture 100 central authorities is not due to
Limited by substrate boundaries condition, therefore suffer from electric field impact and there is larger rotation amplitude.In comparison, neighbouring interior table
The liquid crystal molecule 120 of face 202 and inner surface 302 limited by substrate boundaries condition and LCD alignment compound 110 although
Affected by electric field but only be there is less rotation amplitude.In other words, the liquid crystal molecule 120 near substrate surface is subject to electric field
The electric field that is subject to second substrate central liquid crystal molecule 120 less than first substrate of impact.
Although being attached at inner surface 202 and inner surface 302 in this LCD alignment compound 110, substantially still not yet produce
Raw crosslinking (cross-link), solidification or polymerization.Therefore, now LCD alignment compound 110 remains to by liquid crystal molecule 120
Drive.
Then, reference picture 1D, by external energy E2, such as illumination methods, mode of heating or combinations of the above make liquid crystal
Orientation compound 110 energy absorption, makes first crosslinked functional group's (not illustrating) of any two LCD alignment compounds 110 first
The inner surface 202 of substrate 200 and the inner surface 302 of second substrate 300 form at least one crosslinking bond 112.Consequently, it is possible to i.e.
Make to remove additional voltage, still allow at least part of liquid crystal molecule 120 be bound to above-mentioned tilt angle because of crosslinked bond 112
T.Here, LCD alignment compound 110 can have single or multiple first crosslinked functional group's (not illustrating) can join with another liquid crystal
Produce crosslinked bond 112 to first crosslinked functional group's (not illustrating) of compound 110.Here, crosslinked bond 112 is only shown with dashed box
Meaning property ground represents the mutual crosslinked and fixing state of multiple LCD alignment compounds 110 it should be appreciated that crosslinked bond 112 can regard
By the polymeric web being made up of single or multiple first crosslinked functional group's (not illustrating) of each LCD alignment compound 110
Network.
