Definitions

  • the present invention relates to monomers and oligomers useful as sealants and particularly as one drop fill sealants for liquid crystal applications.
  • the present invention permits assembly of LCD panels without migration of the sealant resin into the liquid crystal or vice versa during LCD assembly and/or curing of the resin.
  • the one drop fill (ODF” ) process is becoming the mainstream process in the assembly of LCD panels in display applications, replacing the conventional vacuum injection technology to meet faster manufacturing process demands.
  • ODF The one drop fill
  • a sealant is dispensed on an electrode-equipped substrate to form a frame of a display element, and liquid crystals are dropped inside the depicted frame.
  • another electrode equipped substrate is joined thereto under vacuum.
  • the sealant undergoes a curing process, either by a combination of UV and thermal or by thermal only process.
  • the ODF method has a few problems in that the sealant material in the uncured state comes into contact with the liquid crystal during the assembly process. This could cause reduction in electro-optical properties of the liquid crystal by resin migration into the liquid crystal or vice versa, or because of ionic impurities that may be present. Hence, design of resin systems for sealant material that show good liquid crystal resistance (less contamination) along with good adhesion and moisture barrier properties has remained a challenge.
  • the present invention relates to unique resins and ODF compositions made therefrom.

Description

CURABLE COMPOSITIONS FOR ONE DROP FILL SEALANT APPLICATION BACKGROUND FIELD
The present invention relates to monomers and oligomers useful as sealants and particularly as one drop fill sealants for liquid crystal applications. In particular， the present invention permits assembly of LCD panels without migration of the sealant resin into the liquid crystal or vice versa during LCD assembly and/or curing of the resin.
BRIEF DESCRIPTION OF RELATED TECHNOLOGY
The one drop fill ( “ODF” ) process is becoming the mainstream process in the assembly of LCD panels in display applications， replacing the conventional vacuum injection technology to meet faster manufacturing process demands. In the ODF process， first， a sealant is dispensed on an electrode-equipped substrate to form a frame of a display element， and liquid crystals are dropped inside the depicted frame. In the next step of the assembly， another electrode equipped substrate is joined thereto under vacuum. Then， the sealant undergoes a curing process， either by a combination of UV and thermal or by thermal only process.
The ODF method has a few problems in that the sealant material in the uncured state comes into contact with the liquid crystal during the assembly process. This could cause reduction in electro-optical properties of the liquid crystal by resin migration into the liquid crystal or vice versa， or because of ionic impurities that may be present. Hence， design of resin systems for sealant material that show good liquid crystal resistance (less contamination) along with good adhesion and moisture barrier properties has remained a challenge.

Normally the thermal free radical initiator with higher decomposition rate is preferred， as this can generate free radicals more easily at common cure temperature (80-130℃) and give faster cure speed， which can reduce the contact time between liquid resin and liquid crystal， and reduce the liquid crystal contamination. On the other hand， ifthe decomposition rate of initiator is too high， the viscosity stability at room temperature will be influenced， thereby reducing the work life of the sealant.
A convenient way of expressing the decomposition rate of an initiator at a specified temperature is in terms of its half-life i.e.， the time required to decompose one-half of the peroxide originally present. To compare reactivity of different initiators， the temperature at which each initiator has a half-life (T1/2) of 10 hours is used. The most reactive (fastest) initiator would be the one with the lowest 10 h T1/2 temperature.
In the present invention， the thermal free radical initiator with 10 h T1/2 temperature of 30-80℃is preferred， and with 10 h T1/2 temperature of 40-70℃is more preferred.
To balance the reactivity and viscosity stability of the composition， the thermal free radical initiator used in the resin composition is in an amount of usually 0.01 to 3 parts by weight， and preferably 0.5 to 2 parts by weight， based on 100 parts by weight of the inventiveresin in the curable composition of the present invention.

Also provided is a method for manufacturing a liquid crystal display having a liquid crystal layer between a first substrate and a second substrate， by means of a liquid crystal one-drop-filling process. The method comprises the steps of
(a) applying the curable composition described in the present invention on a sealing region at periphery of a surface of the first substrate；
(b) dropping liquid crystal on a central area encircled by the sealing region of the surface of the first substrate；
(c) overlaying the second substrate on the first substrate；
(d) optionally performing partial curing by UV-irradiating the curable composition， and
(e) performing final curing by heating the curable composition.
The first substrate and the second substrate used in the present invention are usually transparent glass substrates. Generally， transparent electrodes， active matrix elements (such as TFT) ， alignment film (s) ， a color filter and the like are formed on at least one of the opposed faces of the two substrates. These constitutions may be modified according to the type of the LCD. The manufacturing method according to the present invention may be thought to be applied for any type of the LCD.
In step (a) ， the curable composition is applied on the periphery portion of the surface of the first substrate so as to lap around the substrate circumference in a frame shape. The portion where the curable composition is applied in a frame shape is referred as a seal region. The curable composition can be applied by a known method such as screen printing and dispensing.
In step (b) ， the liquid crystal is then dropped onto the center region surrounded by the seal region in the frame shape on the surface of the first substrate. This step is preferably conducted under reduced pressure.
In step (c) ， said second substrate is then placed over said first substrate， and UV-irradiated in the step (d) . By the UV-irradiation， the curable composition cures partially and shows the strength at a level that displacement does not occur by handling， whereby the two substrates are temporally fixed. Generally， the radiation time is preferably short， for example not longer than 5 minutes， preferably not longer than 3 minutes， more preferably not longer than 1 minute.
In step (e) ， heating the curable composition allows it to achieve the final curing strength， whereby the two substrates are finally bonded. The thermal curing in the step (e) is generally heated at a temperature of 80 to 130℃， and preferably of 100 to 120℃， with the heating time of 30mins to 3 hours， typically 1 hour.
By this process， the major part of the LCD panel is completed.
