In each figure, the components having the same reference numerals have the same configuration. [First Embodiment] Fig. 1 is a plan view showing the configuration of an image display device. In this image display device, as shown in FIG. 1, for example, white light emitted from a lamp 1 of a xenon arc lamp is condensed by the lenses 2 and 3, and is incident on the color separation lens 4. The blue (B) light of the white light incident on the color separation lens 4 passes through the color separation lens 4, and the yellow light is reflected by the color separation lens 4 and enters the color separation lens 5. The red (R) light of the yellow light incident on the color separation lens 5 passes through the color separation lens 5 and is incident on the polarized light 稜鏡 9. The green light (G) of the yellow light incident on the color-resolving lens 5 is reflected by the color-resolving lens 5 and is incident on the polarized light 稜鏡 10. The B light transmitted through the color-resolving lens 4 is incident on the color-resolving lens 7 through the relay lens 6. The B light is reflected by the color-splitting lens 7 and is incident on the polarized light 11 through the relay lens 8. The relay lenses 6, 8 are designed to make the optical path length of B light coincide with the optical path of R light and G light. In addition, since the B light is completely separated at the time when the color-resolving lens 4 is transmitted, a general reflecting lens may be used instead of the color-resolving lens 7. The R light incident on the polarized light 稜鏡 9 reflects only the S polarized light component on its joint surface, and is incident on the reflective liquid crystal element 12 constituting the display panel. The S-polarized light component incident on the reflective liquid crystal element I 2 is modulated and reflected on the reflective liquid crystal element 1 2 (5) 1238285 to become a P-polarized light component. The reflected light from the reflective liquid crystal element 12 is transmitted through the joint surface of the polarized light 稜鏡 9, and is incident on the color synthesis 稜鏡 22 through the spacer glass 41. In addition, the G light incident on the polarized light 稜鏡 10 reflects only the S polarized component on the joint surface, and is incident on the reflective liquid crystal element 13 constituting the display panel. The S-polarized light component incident on the reflective liquid crystal element 13 is modulated and reflected by the polarized light on the reflective liquid crystal element 13, and becomes a P-polarized light component. The reflected light from the reflective liquid crystal element 13 is transmitted through the joint surface of the polarizing prism 10, and is incident on the color synthesizer 22 through the spacer glass 42. In addition, the B light incident on the polarized light 稜鏡 1 1 reflects only the S polarized light component on its joint surface, and is incident on the reflective liquid crystal element 1 4 constituting the display panel. The S-polarized light component incident on the reflective liquid crystal element 14 is modulated and reflected on the reflective liquid crystal element 14 to form a P-polarized light component. The reflected light from the reflective liquid crystal element 14 is transmitted through the joint surface 'of the polarized light 稜鏡 11 to the color combination prism 22 through the spacer glass 43. In addition, each of the reflective liquid crystal elements 12, 13, and 14 applies a voltage corresponding to the displayed image, and the R light, G light, and B light that are incident upon each color component of the displayed image are modulated. The R light, G light, and B light incident on the color combining prism 22 are combined in the color combining 稜鏡 22 and projected onto a screen (not shown) by the projection lens 23. In this way, a portrait is displayed on the screen. Next, the mounting structure of each optical component of the image display device will be described. Reflective liquid crystal elements 12, 13, and 14 each constitute a display liquid crystal element block having a display panel frame] 5 :: I6,17. These display surfaces (6) 1238285 The plate frame 1 5, 16 and 17 are installed in the support frame 丨 8, i 9, 20, respectively. Each of the display panel frames 15, 16, and 17 respectively forms a quadrangular shape, which is opposite to the supporting frame 8, 19, 20. For example, by using a flux 2; [a hot-melt material or a UV-curable resin] The thermosetting material fixes the four corners. In addition, the display panel frames 15, 16, and 17 of the reflective liquid crystal element block are described later. When adjusting the focus position of the projection lens 23 or the relative positions of the reflective liquid crystal elements 1 2, 1 3, and 14. After that, it is fixed on the support frames 18, 19, 20. In this way, the support frames 18, 19, and 20 that hold the reflective liquid crystal element blocks are then fixed to the polarized light beams 9, 9, 10, and 11, respectively. In such a manner that the relative positions of the polarized light 稜鏡 9, 10, 11 and the color composite 稜鏡 22 do not deviate, they are then fixed through spacer glass 41, 42, 43 respectively. That is, the reflective liquid crystal element block and the polarized light 9, 9, 10, and the color composite 稜鏡 22 are all integrated into a block 50. Fig. 2 is a side view showing the structure of a main part of the image display device. In addition, the left-right direction in FIG. 2 is in the first figure, and corresponds to the direction perpendicular to the paper surface in the first figure. Next, a narrow joint plate 44 is fixed to the up-down direction of the color composite plate 22 and the left-right direction in FIG. 2. The projection lens 23 is also screwed to the base 60. The entire system of the lamp 1, projection lens 23, and base 60 above is positioned on the optical base 100, and is fixed by screws or the like. In this image display device, the reflective liquid crystal elements 1 2, 1 3, 1 4 and polarized light 稜鏡 9, 10, 11 and color composite 稜鏡 2 2 constitute a block 50. Therefore, between these optical members, The relative position of is not substantially deviated. Therefore, the optical axis of R light, G light, and B light is not deviated from 1238285 (7), and a good image without registration error can be projected on the screen. Next, the structure of the reflective liquid crystal element blocks holding the reflective liquid crystal elements 12, 13, 14 will be described in more detail. Fig. 3 is an exploded perspective view showing the structure of a reflective liquid crystal element block. Fig. 4 is an oblique view showing the structure of a reflective liquid crystal element block. Since the structures of the reflection-type liquid crystal element blocks having the reflection-type liquid crystal elements 丨 2, 1 3 5 1 4 are common, in the following description, the reflection-type liquid crystal of the representative reflection-type liquid crystal element 12 will be described. Structure of the element block. In the reflective liquid crystal element block, as shown in FIGS. 3 and 4, the reflective liquid crystal element 12 is fixed to the rear portion of the base 61 which is also an aluminum heat sink. The reflective liquid crystal element 12 is connected to the flexible electrode 62. A peripheral portion 6 1 a of the reflective liquid crystal element 12 of the base 6 1 is fixed with a first dust-proof member 63 from the front side of the reflective liquid crystal element 12 by an adhesive or an adhesive. As shown in Fig. 3, a front portion of the first dust-preventing member 63 is provided with a light-shielding plate 64 having an opening formed in a central portion thereof. The light shielding plate 64 is used to prevent light from radiating beyond the effective point of the reflective liquid crystal element 12. A ring-shaped holder 6 6 for holding a wavelength plate (polarizing plate) 6 7 is disposed on the front portion of the light shielding plate 64. A second dust-proof member 65 is disposed between the light shielding plate 64 and the holder 66. The second dust prevention member 6 5 is fixed to an end portion on the side of the light shielding plate 64 of the holder 6 6 with an adhesive or an adhesive. The holder 66 is formed with a gear at a peripheral portion. A wavelength plate 67 is fixed to the end portion, that is, the front end portion, of the holder 66 opposite to the -10- 1238285 (8) light shielding plate 64. In this way, the second dust-proof member 65 and the wavelength plate 67 are integrated with the holder 66. The holder 66 is capable of adjusting the polarization direction of the light irradiated on the reflective liquid crystal element 12 and can rotate around the optical axis while supporting the front surface of the second dust-proof member 65 at the same time as the wavelength plate 67. . In addition, the first and second dust-proof members 6 3, 6 and 5 can be formed of elastic members such as foamed rubber, urethane foam, and vinyl foam. In particular, urethane foams and vinyl foams are moderately elastic, and because they are hardly dusty, they are the best materials. Then, a display panel frame 15 (16, 17) having a circular opening formed in the center of the front portion of the holder 66 is disposed. Screw holes are formed at the four corners of the base 61, the light shielding plate 64, and the display panel frame 15 (1, 6, 17). These bases 61, the light shielding plate 6 4 and the display panel frame 1 5 (1 6, 1 7 ) Is fixed by screws 6 9 as shown in Figure 4. Thus, a reflective liquid crystal element block is formed. In addition, the display panel frame 15 (16, 17) is formed with a window 15a (16a, 17a) for the gear of the holder 66 to face the outside. Therefore, as shown in FIG. 4, when the reflective liquid crystal element block is assembled, the gear train of the holder 66 is faced from the window 15a (16a, 17a) of the display panel frame 15 (16, 17). external. Engage the gears of the other holders 6 and 6 (not shown) with the gears of the holder 6 6. By rotating the toothed car, the holder 6 6 can be rotated around the optical axis, and the reflective liquid crystal element can be easily adjusted. 2 The direction of polarized light. However, the display panel frames 15, 16, and 17 of these reflective liquid crystal element blocks are respectively fixed to the support frame 18, 9, 20, and -11-1238285 (9) on the base 61. Next, position adjustment is performed on the up and down directions, the left and right directions perpendicular to the optical axis, the direction of rotation around the optical axis, and the focus direction along the optical axis. This position adjustment is performed by illuminating each of the reflective liquid crystal elements 12, 13, and 14 and projecting the reflected light from the reflective liquid crystal elements 1 2 51 3, 1 4 on the screen through the projection lens 2 3 so that these reflected light Overlap. Fig. 5 is a front view of the first embodiment of the mounting portion 18, 19, 20 of the support frame 18, 19, and 20 mounted on the reflective liquid crystal element block. After adjusting the position of the reflective liquid crystal element block, as shown in FIG. 5, the panel-side flat portions 15b (16b, 17b) and the support frame 18 provided at the four corners of the display panel frame 15 (16, 17) are made. (19, 20) On the other hand, it is fixed by a hot-melt material such as the flux 21 or a heat-curable material such as an ultraviolet curing resin. A support frame side to which a hot-melt material or a thermosetting material is attached is provided at a position where the support frame 18 (19 J0) and the panel-side flat portion 15b (16b, 17b) of the display panel frame 15, 16, 17 are opposed The flat portion 18a (19a, 20a). These panel-side planar portions 1 5 b (1 6 b, 1 7 b) and the support frame-side planar portions 1 8 a (1 9 a 5 2 0 a) are substantially parallel to each other. Then, these support frame side flat portions 188 (19 & 20) are formed to have a size larger than that of the panel side flat surface portions 15b (16b, 17b) of the display panel frames 15, 16, and 17. That is, the panel-side flat portion 15b (16b, 17b) has a narrower area than the support frame-side flat portion I8a (19a, 20a). Then, the panel-side flat portion 15b (16b, 17b) is provided with a hole portion 70 for allowing at least one or more, that is, one or more hot-melt materials or thermosetting materials to flow into. -12- 1238285 (10) The following describes the procedure for positioning the reflective liquid crystal element block on the support frame. Here, a case where a creamer flux is used as the hot-melt material will be described.

首先,在進行反射型液晶元件區塊的位置調整之前, 在孔部70內及該孔部70的周邊部塗敷乳酯銲劑。然後,在 反射型液晶元件區塊的位置調整之後,從反射型液晶元件 區塊的背面側通過孔部70進行光照射。藉由該光的能源使 乳酯銲劑融溶。然後,藉著冷卻使乳酯銲劑固化,使反射 型液晶元件區塊固定在支持框18(1 9,20)。 此外,即使在使用如紫外線硬化樹脂之熱硬化性材料 時’在進行反射型液晶元件區塊的位置調整之前,在孔部 7〇內及該孔部70的周邊部塗敷紫外線硬化樹脂,在反射型 液晶元件區塊的位置調整之後,從反射型液晶元件區塊的 背面側通過孔部70,進行光照射。藉由該光使紫外線硬化 樹脂硬化,使反射型液晶元件區塊固定在支持框18(1 9,20)First, before adjusting the position of the reflective liquid crystal element block, a creamer flux is applied to the inside of the hole portion 70 and the peripheral portion of the hole portion 70. Then, after the position of the reflective liquid crystal element block is adjusted, light is irradiated through the hole portion 70 from the back side of the reflective liquid crystal element block. The creamer flux is melted by the energy of this light. Then, the creamer flux is solidified by cooling, and the reflective liquid crystal element block is fixed to the support frame 18 (1, 20). In addition, even when using a thermosetting material such as an ultraviolet curable resin, the ultraviolet curable resin is applied to the hole portion 70 and the peripheral portion of the hole portion 70 before the position adjustment of the reflective liquid crystal element block is performed. After the position of the reflective liquid crystal element block is adjusted, light is irradiated through the hole portion 70 from the back side of the reflective liquid crystal element block. This light hardens the ultraviolet-curing resin and fixes the reflective liquid crystal element block to the support frame 18 (1 9, 20)

在該反射型液晶元件區塊中,藉由使熱溶融性材料或 是熱硬化性材料盛入至孔部70內,可使用更多的熱溶融性 材料或是熱硬化性材料,即使在支持框18(19,20)之間有間 隙,亦可確實的固定於支持框18(1 9,20)。 又,在該反射型液晶元件區塊中,由於即使從該反射 型液晶元件區塊的背面側通過孔部7 0對熱融性材料或熱硬 化性材料直接照射光,因此可使熱融性材料迅速融溶或是 使熱硬化性材料迅速硬化。 再者,在該反射型液晶元件區塊中,藉由支持框側平 •13- (11) 1238285 面部1 8 a (1 9 a 5 2 0 a)之面積大於面板側平面部1 5 b (1 6 b,1 7 b), 從反射型液晶元件區塊的背面側照射的光亦照射在支持框 側平面部18a(19a,20a)。因而,加熱支持框側平面部 1 8 a( 19 a,2 0 a),可迅速進行熱融性材料的融溶或是熱硬化 性材料的硬化。 又,在該反射型液晶元件區塊中,藉由支持框側平面 部18a(19a,20a)之面積大於面板側平面部15b(16b,17b),即 使從與反射型液晶元件區塊的支持框側18(1 9,20)相對的位 置偏離時,亦可確保接著面積。 此外,在上述的實施形態中,雖說明藉由照射光加熱 並融溶乳酯銲劑的步驟,惟如銲槍般,接觸熱源並加熱銲 劑使融溶之情況亦可獲得同樣的效果。 〔第2實施形態〕 第6圖係安裝於上述反射型液晶元件區塊的支持框 18,19,20的部分之第2實施形態的正面圖。 在該實施形態中,取代上述實施形態的孔部7 〇,如第 6圖所示,在面板側平面部15b(16b,17b)設置用以使至少一 個以上亦即一或複數個熱融性材料或是熱硬化性材料流入 之缺口部7 1。該缺口部7 1具有比孔部70與面板側平面部 15b(16b,17b)相對更容易形成之優點。 即使在該實施形態中,藉由使熱融性材料或是熱硬化 性材料盛入缺口部7 1內,可使用更多的熱融性材料或是熱 硬化性材料,即使在支持框1 8 (1 9,2 0 )之間具有間隙,亦可 •14- 1238285 (12) 確實固定於支持框1 8 (1 9,2 Ο)。 又,在該反射型液晶元件區塊中,由於即使從該反射 型液晶元件區塊的背面側通過缺口部7 1亦可對熱融性材料 或熱硬化性材料直接照射光,因此可使熱融性材料迅速融 溶或是使熱硬化性材料迅速硬化。 該效果係如銲槍般,在接觸熱源以加熱融溶銲劑之情 況下亦可獲得同樣的效果。 如以上所說明,根據本發明,在具有顯示面板的畫像 顯不裝置中’在附著有熱融性材料或熱硬化性材料的部分 ,於支持框設置附著有熱融性材料或熱硬化性材料之支持 框側平面部略平行且比該支持框側平面部之面積狹窄的面 板側平面部,由於在該面板側平面部設置有用以使至少一 個以上的熱融性材料或熱硬化性材料流入的孔部或缺口部 ,因此即使與支持框相對的位置偏離至各方向,可固定於 .該支持框,且可在短時間內固定。 【圖式簡要說明】 第1圖係顯示畫像顯示裝置的構成之平面圖。 第2圖係顯示畫像顯示裝置的主要構成之側面圖。 第3圖係顯示反射型液晶元件區塊的構造之分解斜視 圖。 第4圖係顯示反射型液晶元件區塊的構造之斜視圖。 第5圖係安裝於上述反射型液晶元件區塊的支持框的 部分之第1實施形態的正面圖。 -15- (13) 1238285 第6圖係安裝於上述反射型液晶元件區塊的支持框的 部分之第2實施形態的正面圖。 〔元件符號說明〕In this reflective liquid crystal element block, by allowing a heat-melting material or a thermosetting material to be contained in the hole portion 70, more heat-melting materials or thermosetting materials can be used. There is a gap between the frames 18 (19, 20), and it can also be fixed to the support frame 18 (1 9, 20). Moreover, in this reflective liquid crystal element block, even if a hot melt material or a thermosetting material is directly irradiated with light through the hole portion 70 from the back side of the reflective liquid crystal element block, the heat-fusible property can be made The material melts quickly or hardens the thermosetting material. Furthermore, in this reflective liquid crystal element block, the area of the face 1 8 a (1 9 a 5 2 0 a) is larger than that of the panel-side flat portion 1 5 b ( 1 6 b, 1 7 b), the light irradiated from the back side of the reflective liquid crystal element block is also irradiated to the support frame side flat portion 18a (19a, 20a). Therefore, heating the support frame side flat portion 1 8 a (19 a, 20 a) can quickly melt the hot-melt material or harden the thermosetting material. In addition, in the reflective liquid crystal element block, since the area of the support frame side flat portion 18a (19a, 20a) is larger than the panel side flat portion 15b (16b, 17b), When the relative position of the frame side 18 (1 9, 20) is deviated, the bonding area can also be secured. In addition, in the embodiment described above, although the step of heating and melting the milk ester flux by irradiating light has been described, the same effect can be obtained even in the case of contacting a heat source and heating the flux like a welding gun. [Second Embodiment] Fig. 6 is a front view of a second embodiment of a portion of the support frame 18, 19, 20 mounted on the above-mentioned reflective liquid crystal element block. In this embodiment, instead of the hole portion 70 of the above embodiment, as shown in FIG. 6, a panel-side flat portion 15b (16b, 17b) is provided to make at least one or more, that is, one or more heat-fusible. The notch 7 1 into which the material or the thermosetting material flows. This notch portion 71 has an advantage that it is relatively easier to form the hole portion 70 and the panel-side flat portion 15b (16b, 17b). Even in this embodiment, by allowing a hot-melt material or a thermosetting material to be contained in the notch portion 71, more hot-melt materials or thermosetting materials can be used, even in the support frame 1 8 There is a gap between (19, 20), or • 14-1238285 (12) It is fixed to the support frame 1 8 (1 9, 2 〇). Moreover, in this reflective liquid crystal element block, even if the notch portion 71 is passed through the notch portion 71 from the back side of the reflective liquid crystal element block, light can be directly irradiated to the hot-melt material or the thermosetting material, so that heat can be applied. Melt materials melt quickly or cause thermosetting materials to harden rapidly. This effect is similar to that of a welding torch. The same effect can be obtained in the case of contacting a heat source to heat a molten solder. As described above, according to the present invention, in an image display device having a display panel, the hot-melt material or the thermosetting material is attached to the support frame at the portion where the hot-melt material or the thermosetting material is attached. The panel side plane portion of the support frame side plane portion which is slightly parallel and narrower than the area of the support frame side plane portion is provided on the panel side plane portion so as to allow at least one or more hot-melt materials or thermosetting materials to flow in. The hole or notch part can be fixed to the support frame even if the position opposite to the support frame deviates to various directions, and can be fixed in a short time.
