DETAILED DESCRIPTION OF THE INVENTION
In the present invention, in order to enable a clear image display during transmissive display, a fluorescent material light emitting layer including a fluorescent material is formed in the transmissive color filter portion. At the time of transmissive display, the fluorescent material emits light by irradiating illumination light having a property of causing the fluorescent material such as black light to emit light well from the backlight light source, thereby realizing a bright and clear display.
[0025]
[Color filter substrate]
First, a color filter substrate to which the present invention is applied will be described. FIG. 1 is a cross-sectional view of a color filter substrate according to an embodiment of the present invention. As described above, the color filter substrate of the present invention is characterized in that a fluorescent material light emitting layer containing a color fluorescent material is provided in a transmission color filter portion.
[0026]
The color filter substrate 10 shown in FIG. 1 is applied to a liquid crystal display panel (described later) having a structure in which a liquid crystal is sandwiched between a pair of translucent substrates via a sealant. 1 shows only the color filter side substrate of the pair of translucent substrates.
[0027]
As shown in FIG. 1, in the color filter substrate 10 of the present embodiment, a resin scattering layer 113 is formed on a translucent substrate 101 made of glass or plastic. As described above, the resin scattering layer 113 is manufactured by forming a light-transmitting resin layer with, for example, acrylic resin on the surface of a substrate such as glass or plastic, and forming a number of fine uneven structures on the surface. be able to.
[0028]
On the resin scattering layer 113, a reflective layer 111 such as an aluminum alloy or a silver alloy is partially formed. The region where the reflective layer 111 is formed is a region used for reflective display (hereinafter also referred to as “reflective region”). Thereby, the surface of the reflective layer 111 becomes an uneven shape reflecting the uneven structure of the resin scattering 113 layer. Therefore, when reflective display is performed using external light, the external light is reflected in a state of being appropriately scattered by the above uneven shape, so that the reflected light can be made uniform and a wide viewing angle can be secured. It becomes.

Further, in the color filter substrate 10 of the present invention, the fluorescent material light emitting layer 130 is formed in a region used for transmissive display (hereinafter also referred to as “transmissive region”), that is, a region where the reflective layer 111 is not formed. It is formed.
[0030]
Then, the color filter 120 is formed on the reflective layer 111 and the fluorescent material light emitting layer 130. Here, the color filter 120 includes a reflective color filter portion 120R and a transmissive color filter portion 120T. That is, the reflective color filter portion 120R is formed on the reflective layer 111 in the reflective region, and the transmissive color filter portion 120T is formed on the fluorescent material light emitting layer 130 in the transmissive region. The reason why the reflective color filter 120R and the transmissive color filter 120T are formed separately is to make it possible to individually adjust display colors during transmissive display and reflective display. A protective layer 127 is formed on the reflective color filter 120R and the transmissive color filter 120T.
[0031]
FIG. 2 shows a plan view of a part of the color filter 120. In FIG. 2, the transmission color filter portions 120T and the reflection color filter portions 120R are alternately formed in the horizontal direction. The transmission color filter portion 120T is formed by repeatedly forming color filter portions 120TR, 120TG, and 120TB corresponding to the respective colors of R (red), G (green), and B (blue) in the vertical direction in FIG. Similarly, the reflective color filter portion 120R is formed by repeatedly forming color filter portions 120RR, 120RG, and 120RB corresponding to R, G, and B, respectively, in the vertical direction in FIG. Further, a black matrix 120B is formed between the color filter portions in order to prevent color mixing between adjacent colors. In the cross-sectional view of FIG. 1, the color filter 120 has a cross section taken along line XX ′ in FIG. That is, the color filter portions in FIG. 1 are of the same color.
[0032]
The fluorescent material light emitting layer 130 formed in the transmissive region is formed in a region corresponding to the transmissive color filter portion 120T (that is, 120TR, 120TG, and 120RB) in FIG. Here, the fluorescent material light emitting layer 130 includes fluorescent material light emitting units 130R, 130G, and 130B corresponding to the three colors R, G, and B, respectively. That is, the fluorescent material light emitting portion 130R corresponding to R (red) is formed in a region corresponding to the red transmissive color filter portion 120TR, and the fluorescent material light emitting portion 130G corresponding to G (green) is the green transmissive color filter. The fluorescent material light emitting unit 130B corresponding to B (blue) is formed in a region corresponding to the blue transmissive color filter unit 120TB.
[0033]
Examples of fluorescent materials constituting the fluorescent material light emitting unit 130 are shown below. As a typical inorganic fluorescent pigment, for example, red as Y ₂ O ₂ S: Eu, blue is Sr ₅ (PO ₄ ) Cl: Eu, green as ZnGeO ₄ : The thing obtained by blending the material containing Mn etc. can be used. In addition, as representatives of organic phosphors (fluorescent dyes), brilliant sulphoflavin FF (yellow), basic yellow HG (yellow), eosin (red), rhodamine 6G (red), rhodamine B (red), etc. should be used. Can do.
[0034]
Then, the protective layer 127 is formed on the color filter 120 as described above.
[0035]
In the reflective display, the color filter substrate 10 configured as described above reflects the external light by the reflective layer 111 and directs it in the direction of the viewer E (see FIG. 3). Recognize images. In the case of transmissive display, light of a short wavelength (for example, 350 nm to 400 nm) such as black light is irradiated from below the color filter substrate 10 by a backlight, and fluorescence of each color constituting the fluorescent material light emitting layer 130 is emitted. Illumination is increased by causing the material to emit light, and display with high definition is enabled.
[0036]
As described above, according to the color filter substrate of the present invention, the color filter portion including the fluorescent material light emitting layer is formed in the transmissive region, and the back side of the color filter substrate (the lower side in FIG. 1) in the transmissive display. Since the fluorescent material light emitting layer emits light by irradiating with black light or the like, a clear color image display can be performed even in a place with low illuminance.
[0037]
[LCD panel]
Next, an embodiment of a liquid crystal display panel to which the color filter substrate of the present invention is applied will be described. This embodiment is an example in which the color filter substrate shown in FIG. 1 is applied to a transflective liquid crystal display panel, and a cross-sectional view thereof is shown in FIG. In FIG. 3, the same components as those in the color filter substrate 10 shown in FIG.
[0038]
In FIG. 3, a liquid crystal display panel 100 includes a substrate 101 made of glass or plastic and a substrate 102 bonded together with a sealant 103, and a liquid crystal 104 is sealed inside. Further, a retardation plate 105 and a polarizing plate 106 are sequentially arranged on the outer surface of the substrate 102, and a retardation plate 107 and a polarizing plate 108 are sequentially arranged on the outer surface of the substrate 101. Note that a backlight 109 that emits illumination light when performing transmissive display is disposed below the polarizing plate 108. The backlight 109 is a black light source that emits black light for causing the fluorescent material light emitting layer 130 to emit light.
[0039]
The substrate 101 constitutes the color filter substrate 10 described with reference to FIG. Specifically, a transparent resin scattering layer 113 is formed on the substrate 101 using, for example, an acrylic resin. Further, on the resin scattering layer 113, the reflective layer 111 is formed in the reflective region, and the fluorescent material light emitting layer 130 is formed in the transmissive region. In the reflective region, the color filter portions 120RR, 120RG, and 120RB for each color are formed on the reflective layer 111 in an arrangement as shown in FIG. 2, for example. On the other hand, in the transmissive region, transmissive color filter portions 120TR, 120TG, and 120TB for each color are formed on the fluorescent material light emitting layer 130.
A black matrix 120B (see FIG. 2) is formed at the boundaries between the reflective color filter portions 120TR, 120TG, and 120TB for each color, and the transmission color filter portions 120RR, 120RG, and 120RB for each color. Is omitted. The black matrix 120B can be formed by superimposing the RGB color filter portions, or can be formed of resin separately from the RGB color filter portions.
[0040]
A protective layer 127 is formed so as to cover the reflective color filter portion 120R and the transmissive color filter portion 120T. The protective layer 127 is for protecting the color filter 120 from corrosion and contamination by chemicals and the like during the manufacturing process of the liquid crystal display panel, and for flattening the surface of the color filter 120.
[0041]
Further, a transparent electrode 114 made of a transparent conductor such as ITO (indium tin oxide) is formed on the surface of the protective layer 127. In the present embodiment, a plurality of the transparent electrodes 114 are formed in stripes arranged in parallel. In addition, the transparent electrode 114 extends in a direction orthogonal to the transparent electrode 121 similarly formed in a stripe shape on the substrate 102, and is included in the intersection region of the transparent electrode 114 and the transparent electrode 121. 100 constituent parts (parts in the intersection region in the reflective layer 111, the color filter 120, the transparent electrode 114, the liquid crystal 104, and the transparent electrode 121) constitute pixels.
[0042]
On the other hand, a transparent electrode 121 is formed on the inner surface of the substrate 102 and is configured to intersect with the transparent electrode 114 on the opposite substrate 101. Note that an alignment film or the like is formed on the transparent electrode 114 on the substrate 101 and the transparent electrode 121 on the substrate 102 as necessary.
[0043]
In the liquid crystal display panel 100, when reflective display is performed, external light incident on the region where the reflective layer 111 is formed travels along the path R shown in FIG. Reflected and viewed by an observer. On the other hand, when transmissive display is performed, illumination light such as black light emitted from the backlight 109 is incident on the transmissive region, so that the fluorescent material in the fluorescent material light emitting layer 130 formed in the transmissive region emits light. Let The light emitted thereby travels as indicated by the path T and is visually recognized by the observer.
[0044]
Black light is light obtained by taking out light having a wavelength of near ultraviolet light (for example, around 300 to 450 nm) with a specially designed ultraviolet filter or the like, and when irradiated to an object containing a phosphor or a fluorescent material, the black light is fluorescent. The body and fluorescent material emit light. Examples of the backlight 109 that emits black light include a fluorescent tube, a fluorescent material that extracts ultraviolet light having the above wavelength, and an ultraviolet filter. In the present invention, the structure of the backlight 109 that emits black light is not limited, and various light sources can be used.
[0045]
In the present invention, the arrangement of the color portions of the color filter is not limited to the arrangement shown in FIG. That is, various arrangements such as a stripe arrangement, a delta arrangement, and a diagonal arrangement can be formed. In the above embodiment, the transmissive color filter and the reflective color filter are independently formed of different materials, but can be formed as a single color filter with the same material. In this case, the present invention can also be applied to a type of color filter in which the thickness of the color filter is changed between the transmission region and the reflection region.
[0046]

A fine uneven shape is formed on the surface of the glass substrate. Further, by heat-treating the unevenness formed on the glass substrate, the uneven shape corners are deformed by heat to form a smooth uneven shape. As a method for forming the resin scattering layer 113, it is of course possible to employ other methods.
[0048]
