Description

Polymerizable composition, cured film thereof, and optical member and display device including the same

[0001] The present invention relates to a polymerizable composition, a cured film thereof, and an optical member and a display device comprising the same.

[0002] There is a growing need to improve light efficiency in OLEDs (Organic Light Emitting Diodes) and image sensors. Recently, research and development on refractive index-controlled optical films has been actively underway as a technology essential for improving OLED lifespan and increasing battery efficiency.

[0003] The theoretical lower limit of the low refractive index range controllable by organic compounds is known to be around 1.40 second. When hollow silica is mixed, the refractive index is lowered, but due to compatibility issues with organic compounds, problems such as reduced transmittance, haze, and adhesion between the upper and lower films occur. Furthermore, the increased viscosity of the composition leads to problems such as reduced inkjet processability, resulting in many technical limitations.

[0004] In addition, as bezels on smartphones and the like have recently become thinner, there is insufficient area to absorb external shocks, leading to delamination of the underlying layer due to external impact. Conventional inkjet compositions that obtain a cured film by polymerizing only with UV irradiation do not undergo separate heat curing, so they have the problem of weak adhesion to the underlying layer due to such external shocks.

[0005] In addition, the metal layer is corroded by adjacent layers, causing problems with durability and performance, and improvements are being requested.

[0006] The present invention aims to provide a polymerizable composition that can improve corrosion of a metal layer even when in close proximity to a metal layer by including one or more monomers containing polymerization groups and a light stabilizer of an amine compound, provides refractive properties suitable for low or high refractive index applications, has excellent haze properties, can improve curability, and has excellent printability, a cured film thereof, and an optical member and a display device including the same.

[0195] Meanwhile, according to one embodiment of the present invention, when the cured film uses a high-refractive index monomer, the refractive index may be 1.58 or higher. Specifically, the cured film may have a refractive index of 1.58 or higher, more specifically 1.61 or higher, measured for a wavelength (average) of 555 to 575 nm. Since the cured film exhibits high low-refractive index characteristics with a refractive index of 1.58 or higher, it is possible to realize an optical member and a display device with excellent optical properties.

[0196] One embodiment of the present invention provides an optical member comprising the hardened film.

[0197] According to one embodiment of the present invention, the optical member can realize excellent optical properties and coating properties by including the cured film. In addition, the optical member can effectively suppress corrosion and discoloration even under high temperature and high humidity conditions, thereby having excellent durability and lifespan characteristics.

[0198] According to one embodiment of the present invention, the optical member may include a substrate; and the cured film provided on the substrate. Additionally, the cured film may be formed by photocuring after the polymerizable composition is applied onto the substrate by an inkjet process. In this case, a well-known substrate, such as bare glass, may be used as the substrate.

[0199] In addition, the optical member may be manufactured by applying the polymerizable composition onto the substrate using a Mayer bar, a coating applicator, or an inkjet device, and then exposing it to light using an LED lamp or a metal halide lamp in an air atmosphere to proceed with photocuring. At this time, the polymerizable composition may be applied in a single film form and then photocured to form an optical member in the form of a general optical film, but if necessary, it may also be applied using the inkjet device to form a specific pattern and then photocured. In this case, the optical member may take the form of a pattern film having a cured film patterned in a polyhedral shape, such as a prism structure, formed on the substrate.

[0200] One embodiment of the present invention provides a display device comprising the cured film as at least one of an optical film and a pattern film.

[0201] The display device according to one embodiment of the present invention can exhibit excellent optical characteristics.

[0202] The optical member, such as the optical film or pattern film, may have a general thickness depending on its type or the structure of the applied display element, and, for example, may have a thickness that is controlled within the range of 0.01 μm to 1000 μm.

[0203] The configuration of a display device to which the optical member, such as the above-mentioned optical film or pattern film, is applied may follow a conventional configuration well known in the art, except that the above-mentioned cured film is applied to the above-mentioned optical member; therefore, further explanation regarding this is omitted.

[0204] Hereinafter, the present invention will be described in detail with reference to examples to specifically explain the invention. However, the embodiments according to the present invention may be modified in various different forms, and the scope of the present invention is not to be interpreted as being limited to the embodiments described below.

[0253] ○: When the haze measurement value is 0.5 to 1.0 or less

[0254] X: When the haze measurement value is greater than 1.0

[0255] Experimental Example 4) Conversion Measurement

[0256] The absorbance of the cured film before and after exposure was measured by comparing the results using an FT-IR spectrophotometer. 1690–1780 cm⁻¹ -1 The C=O peak and 780–840 cm⁻¹ -1 The conversion rate was calculated by integrating the C=C peak.

[0257] Decision

[0258] ◎ : 95% or more

[0259] ○ : 90~95%

[0260] X : Less than 90%

[0261] Experimental Example 5) Transmittance Measurement

[0262] The average transmittance of the 10㎛ thick cured film formed on the bare glass substrate was measured at 380–780 nm using a UV-VIS spectrophotometer (Cary4000, Agilent).

[0263] Decision

[0264] ○: When the average transmittance value is 98% or higher

[0266] Experimental Example 6) Measurement of Viscosity (Absolute Viscosity)

[0281] X: When the Modulus value is outside the range of 0.1 to 0.5 GPa

[0282]

[0283]

[0284] As can be seen from the results in Table 8 above,

[0285] It can be confirmed that the polymerizable composition according to one embodiment of the present invention exhibits superior characteristics regarding metal corrosion, haze, conversion, transmittance, and modulus, as well as superior viscosity and inkjet properties, compared to the polymerizable composition of the comparative example. Furthermore, it has been confirmed that the polymerizable composition according to one embodiment of the present invention can be excellently applied to both low-refractive index polymerizable compositions and high-refractive index polymerizable compositions.

[0286] In particular, Examples 1, 2, 4, 7, 10, 13 to 16, 20, 39, 40, 43 to 46, 70, and 71 had the best overall characteristics.

[0287] In contrast, in the case of Examples 25 to 38, the light stabilizer lacked acrylate functional groups, so the degree of crosslinking was reduced, and consequently, unreacted light stabilizer rose toward the surface of the film and absorbed moisture, causing some haze to occur.

[0288] In addition, in the case of Examples 47 to 50, the second high-flexibility monomer had an ethylene oxide structure, so some haze occurred due to moisture absorption and the inkjet performance was somewhat degraded.

[0289] In addition, in the case of Examples 77 to 82, the light stabilizer content was excessive, resulting in reduced conversion rate, haze, and inkjet characteristics, and in the case of Examples 83 to 92, the ratio of the content of each component was not optimized, resulting in reduced performance.

[0290] When comparing the embodiments and comparative examples of the present invention,

[0291] Comparative Examples 1 to 8 did not contain a light stabilizer, so the metal corrosion, haze, and modulus characteristics were significantly reduced.

[0292] A person skilled in the art will be able to fully understand the effects of the present invention from the experimental results of the above examples and comparative examples and Table 6.
