These embodiments are provided as examples so that this disclosure will be thorough and complete, and will fully convey the aspects and features of the present invention to those skilled in the art. Accordingly, processes, elements, and techniques that are not necessary to those having ordinary skill in the art for a complete understanding of the aspects and features of the present invention may not be described.
- In the drawings, relative sizes, thicknesses, etc. of layers, elements, regions, and areas may be illustrated in an enlarged manner for clarity and ease of description thereof. When a layer, area, or plate is referred to as being “on” another layer, area, or plate, it may be directly on the other layer, area, or plate, or intervening layers, areas, or plates may be present therebetween. Conversely, when a layer, area, or plate is referred to as being “directly on” another layer, area, or plate, intervening layers, areas, or plates may be absent therebetween. Further when a layer, area, or plate is referred to as being “below” another layer, area, or plate, it may be directly below the other layer, area, or plate, or intervening layers, areas, or plates may be present therebetween. Conversely, when a layer, area, or plate is referred to as being “directly below” another layer, area, or plate, intervening layers, areas, or plates may be absent therebetween.
- The spatially relative terms “below”, “beneath”, “less”, “above”, “upper” and the like, may be used herein for ease of description to describe the relations between one element or component and another element or component as illustrated in the drawings. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation, in addition to the orientation depicted in the drawings. For example, in the case where a device illustrated in the drawing is turned over, the device positioned “below” or “beneath” another device may be placed “above” another device. Accordingly, the illustrative term “below” may include both the lower and upper positions. The device may also be oriented in the other direction and thus the spatially relative terms may be interpreted differently depending on the orientations.
- Throughout the specification, when an element is referred to as being “connected” to another element, the element is “directly connected” to the other element, or “electrically connected” to the other element with one or more intervening elements interposed therebetween.
- The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting of the present invention. As used herein, the singular forms “a” and “an” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises,” “comprising,” “includes” and/or “including,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components and/or groups thereof. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. Expressions such as “at least one of,” when preceding a list of elements, modify the entire list of elements and do not modify the individual elements of the list.
- It will be understood that, although the terms “first,” “second,” “third,” and the like may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. Thus, “a first element” discussed below could be termed “a second element” or “a third element,” and “a second element” and “a third element” may be termed likewise without departing from the teachings herein.
- “About” or “approximately” as used herein is inclusive of the stated value and means within an acceptable range of deviation for the particular value as determined by one of ordinary skill in the art, considering the measurement in question and the error associated with measurement of the particular quantity (i.e., the limitations of the measurement system). For example, “about” may mean within one or more standard deviations, or within ±30%, 20%, 10%, 5%, etc. of the stated value.
- Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by those skilled in the art to which this invention pertains. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an ideal or excessively formal sense unless clearly defined in the present specification.
- Further, the use of “may” when describing embodiments of the present invention refers to “one or more embodiments of the present invention.” In addition, the use of alternative language, such as “or,” when describing embodiments of the present invention, refers to “one or more embodiments of the present invention” for each corresponding item listed. As used herein, the terms “use,” “using,” and “used” may be considered synonymous with the terms “utilize,” “utilizing,” and “utilized,” respectively.

- Hereinafter, a first exemplary embodiment is described with reference to
FIG. 1 . -
FIG. 1 is a cross-sectional view illustrating aplastic substrate 101 according to a first exemplary embodiment. - The
plastic substrate 101 according to the first exemplary embodiment includes aplastic support member 110 having light transmittance and a first organic-inorganic hybrid layer 121 on theplastic support member 110. - A plastic film having light transmittance may be utilized as the
plastic support member 110. For example, a polycarbonate (PC) film, a polyacrylic film, a polymethyl methacrylate (PMMA) film, a polyimide (PI) film, a polyethylene (PET) film, a polypropylene (PP) film, a polystyrene (PS) film, a polyamide (PA) film, a polyacetal (POM) film, a polybutylene terephthalate (PBT) film, a cellulose film and/or an acrylic-polycarbonate copolymer alloy film may be utilized as theplastic support member 110. - For example, a film including a copolymer of PC and PMMA may be used as the
plastic support member 110. The copolymer of PC and PMMA may include PC in an amount ranging from about 50 percent by weight (wt %) to about 70 wt % and PMMA in an amount ranging from about 30 wt % to about 50 wt %. For example, a film including a copolymer of PC and PMMA in a weight ratio of 6:4 may be utilized as theplastic support member 110. - The
plastic support member 110 may have a thickness ranging from about 400 μm to about 1000 μm. When the thickness of theplastic support member 110 is less than about 400 μm, the supporting strength may be relatively weak (or weakened), and when the thickness is greater than about 1000 μm, it is disadvantageous for slimming down the device (or the device may be relatively thick). - The first organic-
inorganic hybrid layer 121 may include a first organic-inorganic hybrid matrix 120 and anion 150 implanted into the first organic-inorganic hybrid matrix 120. - The first organic-
inorganic hybrid matrix 120 may include a polymer resin and a silicone resin. - The polymer resin may include at least one of an acrylic resin, a urethane resin and/or a urethane-acrylate resin. For example, a urethane-acrylate copolymer resin may be utilized as the polymer resin. However, the polymer resin is not limited thereto.
- The silicone resin may include at least one of a monomer represented by the following Chemical Formula 1 and a monomer represented by the following Chemical Formula 2. For example, the silicone resin may be formed by polymerization of a composition including at least one of the monomer represented by the following Chemical Formula 1 and the monomer represented by the following Chemical Formula 2.
- In Chemical Formula 1, respective ones of R21, R22, R23 and R24 are one of an amino group, an epoxy group, a phenyl group, an acryl group and/or a vinyl group, and respective ones of R25 and R26 are hydrogen (H) and/or a hydrocarbon group having 1 to 6 carbon atoms.
- For example, the first organic-
inorganic hybrid matrix 120 may be formed by polymerization of a polymerizable composition including a polymer resin-forming monomer and/or a silicone resin-forming monomer. - The first organic-
inorganic hybrid layer 121 has a thickness ranging from about 2 μm to about 20 μm. - When the thickness of the first organic-
inorganic hybrid layer 121 is less than about 2 μm, the first organic-inorganic hybrid layer 121 may not have sufficient strength and ion implantation may be difficult (or may not be easy). In addition, when the thickness of the first organic-inorganic hybrid layer 121 is greater than about 20 μm, it is disadvantageous for slimming down the device (or the device may be relatively thick). - The
ions 150 may be implanted at (or on) a side of the first organic-inorganic hybrid matrix 120 that is opposite to theplastic support member 110. For example, theions 150 may be implanted through asurface 120 a of the first organic-inorganic hybrid matrix 120 at (or on) an opposite side from theplastic support member 110. - An amount (or quantity) of
ions 150 implanted into the first organic-inorganic hybrid matrix 120 may range from about 2×1013/cm2 to about 2×1014/cm2. The amount ofions 150 is expressed by the number of ions per unit area (cm2). Hereinafter, an amount ofions 150 per unit area is referred to as an “ion amount”. - When the ion amount is less than about 2×1013/cm2, the hardness and strength of the first organic-
inorganic hybrid layer 121 may be relatively low (or lower than desired). In addition, when the ion amount exceeds about 2×1014/cm2, yellow shift, i.e., a color shift toward yellow, may occur. - The
ions 150 implanted into the first organic-inorganic hybrid matrix 120 may include at least one of boron (B) ions and nitrogen (N) ions. The condition for boron (B) ion implantation and the condition for nitrogen (N) ion implantation may be different from each other. - An implantation depth of the
ions 150 may be in a range from about 300 nm to about 400 nm. The implantation depth of theions 150 is represented by a distance dl from thesurface 120 a. - According to the first exemplary embodiment, the ion amount of about 2×1013/cm2 or more is maintained from the
surface 120 a of the first organic-inorganic hybrid matrix 120 to a depth of about 300 nm to about 400 nm (or such that the distance dl is about 300 nm to about 400 nm). - When the implantation depth of the
ions 150 is less than about 300 nm, strength of the first organic-inorganic hybrid layer 121 may be insufficient (or relatively low). Further, when theions 150 should be implanted with high energy (or relatively high energy) in order to implantions 150 at an implantation depth of more than about 400 nm. In such an exemplary embodiment, the first organic-inorganic hybrid layer 121 may be damaged. - According to the first exemplary embodiment, the
ions 150 are implanted at an energy ranging from about 60 keV to about 80 keV. When the ion implantation energy is less than about 60 keV, an ion implantation efficiency is lowered. In addition, when the ion implantation energy exceeds about 80 keV, the first organic-inorganic hybrid layer 121 may be damaged during the ion implantation process. - The first organic-
inorganic hybrid layer 121 may further include fluorine (F) in an amount ranging from about 0.001 wt % to about 0.2 wt % with respect to the total weight of the first organic-inorganic hybrid layer 121. In addition, an anti-finger layer may be provided on the first organic-inorganic hybrid layer 121. - A second exemplary embodiment is described below with reference to

inorganic layer 131 is not particularly limited. For example, the firstinorganic layer 131 may include a layer including an inorganic material. - The first
inorganic layer 131 may include, for example, a silicone resin. In addition, the firstinorganic layer 131 may include a polymer resin and inorganic particles dispersed in the polymer resin. For example, the firstinorganic layer 131 may include a polymer resin and silicon oxide (SiOx) dispersed in the polymer resin. - When the first
inorganic layer 131 includes a polymer connection group, theplastic support member 110 and the firstinorganic layer 131 may have a strong bonding force. - The first
inorganic layer 131 may have a thickness ranging from about 3 μm to about 10 μm. When the thickness of the firstinorganic layer 131 is less than about 3 μm, the strength of theplastic substrate 102 may be relatively weak (or weakened). In addition, when the thickness of the firstinorganic layer 131 is greater than about 10 μm, it may be disadvantageous to slim down the device (or the device may be relatively thick). - Hereinafter, a third exemplary embodiment is described with reference to
FIG. 3 . -

organic layer 141 may serve as a buffer for stress generated between layers. - The first
organic layer 141 may have a thickness ranging from about 5 μm to about 10 μm. When the thickness of the firstorganic layer 141 is less than about 5 μm, an interlayer buffer effect may be reduced.

- The evaluation methods of physical properties illustrated in Table 1 are as follows.
- The pencil hardness is evaluated in accordance with the pencil hardness test specified in JIS K 5600-5-4. For example, the pencil hardness is measured five times on the sample with respect to a weight of 1 kg, and the smallest value is selected as a pencil hardness of the sample.
- In the pencil hardness, the reference marks “H,” “F” and “B,” initials of “hard,” “firm,” and “black,” respectively, represent hardness and concentration. As a number of an “H” lead or a “B” lead increases, the “H” lead becomes harder, whereas the “B” lead becomes smoother. That is, “9H” denotes a highest hardness, and the hardness decreases in the following order: 8H, 7H, 6H, 5H, 4H, 3H, 2H, H, F, B, 2B, 3B, 4B, 5B, 6B, 7B, 8B and 9B.
- For evaluation of the optical characteristics, transmittance and reflectance are measured using a spectrophotometer (exemplary device name: “COH-400”).
- For appearance evaluation, discoloration of the sample is visually identified. For example, it is evaluated whether or not the yellow shift is observed in the sample.
- The reference mark “YI” indicates a yellow index. The larger the YI value is, the larger the yellow shift.
- The chromaticity (b*) represents the yellow shift according to the CIE 1976(L*,a*,b*) color coordinates. Herein, a positive value of 1b* corresponds to the degree of yellow shift and a negative value of 1b* corresponds to the degree of blue shift.
- Referring to Table 1, in particular, Sample 1, Sample 6 and Sample 7 are evaluated to have excellent physical properties.
- In addition, nitrogen (N) ions are implanted into the first organic-
inorganic hybrid matrix 120 of each sample according to the ion implantation conditions illustrated in Table 2 below to produce a plastic substrate. The evaluation results of the physical properties are illustrated in Table 2. -

The scratch resistance evaluation method using a steel wool is as follows. A sample having a size of 200 mm×200 mm is manufactured using a plastic substrate. In addition, a cylinder having a diameter of about 25 mm and a flat surface having a steel wool #0000 uniformly attached thereto is prepared. Subsequently, a surface of the sample is rubbed back and forth six hundred times with the flat surface of the cylinder having the steel wool #0000 thereon, with a weight of about 1.0 kg at a speed of about 100 mm a second, and the depth and width of scratches generated on the surface of the sample are measured. The scratch resistance evaluation results for Reference Example 1 and Samples 1, 6 and 9 are shown in
FIG. 9 . - Referring to
FIG. 9 , samples 6 and 9 have particularly excellent scratch resistance. -
FIG. 10 shows the results of a vibration abrasion resistance evaluation. - For evaluating vibration abrasion resistance, a commercially available vibration abrasion tester (e.g., a Rösler vibration abrasion tester) is utilized. Vibration and abrasion are applied to the sample by using the vibration abrasion tester. The abrasion resistance is evaluated by the ratio of abrasion resistance of samples to glass over time.
