  However, in the mounting case having a configuration in which the protrusions provided on the side surface of the cover as described above are fitted to the hooks of the plate, due to manufacturing tolerances for enabling such fitting, the cover and The relative positional relationship with the plate may be shifted. For this reason, there is a technical problem in that the relative positional relationship between the electro-optical device and the plate that are typically bonded and fixed to the cover is shifted, and accurate projection display may be difficult. .

  The present invention has been made in view of, for example, the above-described problems, and can reduce the displacement of the relative positional relationship between the mounting case and the electro-optical device and can display an image with higher quality. Provided are an electro-optical device mounting case for mounting the device, an electro-optical device in which the electro-optical device is housed in the mounting case, and an electronic apparatus such as a liquid crystal projector including the electro-optical device. This is the issue.

  In order to solve the above problems, an electro-optical device mounting case according to the present invention is an electro-optical device mounting case for accommodating an electro-optical device having a plurality of pixels in a pixel region on a substrate. A plate body disposed to face one surface of the optical device, and a first engagement portion provided at a position corresponding to each of the one side of the substrate and the other side facing the one side of the plate body. A plate having a cover, a cover main body disposed so as to cover the plate main body and the electro-optical device, and a second engagement portion provided on the cover main body and engageable with the first engagement portion. A cover, wherein the first engagement portion presses at least a portion of the first engagement portion against the second engagement portion along a first direction along the one side. Said cover of the plate Against a positioning means for positioning.

  According to the mounting case for an electro-optical device of the present invention (hereinafter abbreviated as “mounting case” as appropriate), light from a light source is emitted from a light source to a pixel region in which a plurality of pixels are arranged on a substrate such as a glass substrate or a quartz substrate. An incident electro-optical device is accommodated. Examples of such an electro-optical device include a liquid crystal device or a liquid crystal panel mounted as a light valve in a projection display device.

  The mounting case of the present invention includes a plate and a cover. For example, when such a mounting case accommodates a transmissive electro-optical device that transmits light, the plate main body portion that is disposed so as to face the electro-optical device of the plate has a first pixel corresponding to the pixel region. One opening is opened, and a second opening corresponding to the pixel region is opened in the cover main body arranged to cover the plate main body and the electro-optical device in the cover. Due to the presence of the first and second openings, light can be incident from outside the mounting case to the electro-optical device, and light can be emitted from the electro-optical device to the outside of the mounting case. . The electro-optical device is typically fixed by being adhered to the cover with an adhesive, for example, while being covered with the cover.

  In this invention, the 1st engaging part is provided in the position corresponding to each of the one side of the board | substrate in a plate main-body part, and the other side facing this one side. That is, the first engagement portion is viewed from the side facing one surface of the electro-optic device (in other words, the substrate surface of the substrate). Are provided near the center of each. Further, the cover main body portion is provided with a second engagement portion that can be engaged with the first engagement portion, and the relative positional relationship between the cover and the plate is the first engagement portion and the second engagement portion. Maintained by the engagement between.

  Particularly in the present invention, the first engagement portion is configured to press the at least part of the first engagement portion against the second engagement portion along the first direction along the one side, thereby covering the plate. Positioning means for positioning with respect to. That is, for example, the first engaging portion has an elastic portion capable of exerting an elastic force along the first direction, and the elastic portion is brought into contact with a part of the second engaging portion. An elastic force is exhibited along the first direction so that at least a part of the first engaging part can be pressed against another part of the second engaging part.

  Therefore, the displacement of the relative positional relationship between the cover and the plate in the first direction, which may occur due to manufacturing tolerances for enabling the first and second engaging portions to engage with each other, is almost or completely eliminated. It can be lost. That is, the relative positional relationship between the cover and the plate in the first direction can be reliably maintained by the positioning means of the first engagement portion. Therefore, for example, it is possible to reduce or prevent the position of the first opening portion opened in the plate main body portion from shifting along the first direction with respect to the pixel region of the electro-optical device fixed to the cover. In other words, the positional relationship between the pixel region of the electro-optical device (and the second opening of the cover main body) and the first opening of the plate main body can be stabilized. Accordingly, when the electro-optical device housed in the mounting case is mounted as a light valve in a projection display device, for example, the relative positional relationship between the cover, the plate, and the electro-optical device in the first direction is shifted. Therefore, for example, it is possible to reduce or prevent light from being blocked more than necessary by a cover or a plate or from causing light leakage. As a result, high-quality image display can be performed by the electro-optical device housed in the mounting case.

  As described above, according to the mounting case of the present invention, the relative positional relationship between the mounting case and the electro-optical device can be reduced. As a result, a high-quality image can be displayed by the electro-optical device housed in the mounting case.

Furthermore, the relative positional relationship in the 1st direction of a 1st and 2nd opening part can be reliably maintained by a positioning means. Therefore, for example, it is possible to reduce or prevent light from being blocked more than necessary by a cover or a plate or from causing light leakage.

  In another aspect of the mounting case for an electro-optical device of the present invention, the second engaging portion is provided on a side portion surrounding a side edge of the electro-optical device in the cover main body portion, and the outer surface side of the side portion.

  In this case, the positioning of the plate with respect to the cover can be suitably performed by the positioning means. Furthermore, by positioning the hook portion against only a part of the convex portion toward only one side in the first direction, positioning of the plate with respect to the cover can be realized with a relatively simple configuration. it can.

  In the above-described aspect in which the second engaging portion is formed as a concavo-convex portion and the first engaging portion has a hook portion, the hook portion is arranged in a line along the first direction. The positioning means includes a first convex portion as a part of the convex portion toward the side different from the side where the second hook portion is located in the first direction. A second convex portion as another part of the convex portion toward the side different from the side where the first hook portion is located in the first direction. You may comprise so that it may press on.

  In this case, the positioning of the plate with respect to the cover can be suitably performed by the positioning means.

  In the aspect in which the hook portion includes the first and second hook portions described above, the first convex portion includes the first convex portion main body against which the first hook portion is pressed, and the first convex portion main body than the first convex portion main body. A first extending portion formed on the plate main body side and extending toward the second convex portion side along the first direction, the second hook portion being pressed against the second convex portion; A second projecting portion main body and a second extending portion that is formed closer to the plate body portion than the second projecting portion main body and extends toward the first projecting portion side along the first direction. You may comprise as follows.

  In this case, the first and second extending portions can reduce or prevent the plate from shifting toward the plate main body with respect to the cover. That is, the first engagement portion and the second engagement portion can be reliably engaged with each other. Therefore, it can reduce or prevent that a plate and a cover remove | deviate from each other.

  In the above-described aspect in which the second engaging portion is formed as a concavo-convex portion and the first engaging portion has a hook portion, the hook portion is arranged in a line along the first direction. The positioning means includes a third protrusion formed at a position corresponding to the first and second hook portions in the first direction in the first direction. You may comprise so that it may each press with respect to a part.

Furthermore, the positioning of the plate with respect to the cover can be suitably performed by the positioning means.

  In another aspect of the mounting case for an electro-optical device according to the aspect of the invention, the first engaging portion includes an elastic portion capable of exerting an elastic force along the first direction as a part of the positioning unit.

  According to this aspect, for example, at least a part of the first engagement portion can be reliably pressed against the second engagement portion by the elastic portion having a spring structure. Therefore, the relative positional relationship between the cover and the plate in the first direction can be reliably maintained.

  In the above-described aspect in which the second engaging portion is formed as a concavo-convex portion and the first engaging portion has a hook portion, the second engaging portion is a part of the convex portion, and the first portion is formed on the side portion. Two projecting portions arranged to be different in length in the second direction intersecting with each other and having one end aligned on a side different from the plate main body side in the second direction, and the hook portion includes The first engaging part is formed as a part of the positioning means at a position corresponding to the position between the two convex parts, and is provided so as to surround the two convex parts. Of these, it may be configured to have an elastic portion capable of exerting an elastic force along the first direction by contacting the longer convex portion.

  In this case, the second engaging portion has a length extending in the second direction intersecting in the first direction at the side portion (that is, the direction intersecting the substrate surface of the substrate or the direction intersecting one surface of the electro-optical device). Two different convex portions are included. The two convex portions are arranged so that one ends thereof are aligned with each other on a side different from the plate main body side in the second direction. Therefore, by hooking the hook portion to the one end of the two convex portions, it is possible to reliably reduce or prevent the plate from being displaced toward the plate main body with respect to the cover.

  Furthermore, the first engaging portion has an elastic portion capable of exerting an elastic force along the first direction. The elastic part is brought into contact with the longer convex part of the two convex parts, whereby the elastic force of the elastic part is exerted, and at least a part of the first engaging part is It can be surely pressed against the two engaging portions.

  In addition, since the elastic portion is formed at a position corresponding to between the two convex portions, the elastic portion and the two convex portions overlap each other when viewed from the outer surface side of the side portion. Can be reduced or prevented. Accordingly, it is possible to reduce or prevent the elastic portion from being deformed so as to be directed to the outer surface side by overlapping the two convex portions. Therefore, it can suppress or prevent that the elastic force by an elastic part reduces.

  In addition, the elastic part is brought into contact with the longer convex part of the two convex parts. In other words, of the two convex portions, the length of the convex portion that does not contact the elastic portion is shorter than the length of the convex portion that contacts the elastic portion. Therefore, when engaging the first engagement portion and the second engagement portion, the hook portion is deformed so as to be directed toward the outer surface by the convex portion on which the elastic portion is not abutted. Can be reduced. Furthermore, it is possible to reduce the occurrence of a situation in which the elastic portion may not be brought into contact with the longer convex portion, which may be caused by the deformation of the hook portion.

  In this case, the elastic portion can be easily brought into contact with the longer convex portion by inserting the elastic portion between the two convex portions from the plate main body side, and the elastic force along the first direction is applied. It can be demonstrated reliably.

  In the aspect in which the hook portion is provided so as to surround the two convex portions as described above, at least one of the two convex portions gradually decreases in the protruding thickness as it approaches the plate body portion side. You may comprise so that it may have a taper part.

  In this case, when engaging the first engagement portion and the second engagement portion, the hook portion can be easily disposed so as to surround the two convex portions. That is, the hook portion can be disposed so as to surround the two convex portions without being substantially disturbed by the thickness of the two convex portions on the plate main body side.

  In order to solve the above problems, the electro-optical device of the present invention includes the above-described mounting case for the electro-optical device of the present invention, and is accommodated in the mounting case for the electro-optical device.

Due to the presence of these windows 615 and 715, it is possible to allow light to enter the electro-optical device 500 from outside the mounting case 810, and it is possible to emit light from the electro-optical device 500 to the outside of the mounting case 810. It becomes. In other words, the peripheral region located around the pixel region 10 a in the electro-optical device 500 in the state of being accommodated in the mounting case 810 is covered with the plate 610 and the cover 710. For this reason, the plate 610 and the cover 710 have a light blocking function for preventing light leakage in the peripheral region or preventing stray light from entering the pixel region 10a from the peripheral region. In this embodiment, it is assumed that light enters from the cover 710 side, passes through the electro-optical device 500, and exits from the plate 610 side. That is, in FIG. 1, it is not the cover 710 but the plate 610 that faces the dichroic prism 1112.

The plate 610 and the cover 710 are assembled by such engagement between the engaging portions 612 and 627. Thereby, the structure of the mounting case 810 becomes more rigid (that is, the plate 610 and the cover 710 are not easily separated). The configuration of the engaging portions 612 and 712 will be described in more detail later.

  As described above, the electro-optical device 500 is accommodated in the internal space of the cover 710 and is mounted on the mounting case 810 by fixing the plate 610 to the cover 710 by the engagement between the engaging portions 612 and 712. The

FIG. 6 is a side view of the mounting case viewed from the direction of the arrow X in FIG. 5 in a state where the electro-optical device is accommodated. FIG. 7 is an enlarged view showing a portion surrounded by a broken line L1 in FIG. 8 is a cross-sectional view taken along the line AA ′ of FIG.

5 and 6, the cover 710 is made of metal such as aluminum, resin, or the like, and includes an engaging portion 712 on a side surface of the cover main body portion 711. More specifically, the engaging portion 712 is arranged on the side portion of the cover main body portion 711 located on the side surface (that is, the side portion of the cover main body portion 711 along the side edge of the electro-optical device 500). Groove part 350 dug along the direction (that is, the direction intersecting the front surface of mounting case 810), convex parts 311a and 311b defining groove part 350, and a claw projecting to the outer surface side of the side part in groove part 350 It consists of parts 320 and 330. The convex portions 311a and 311b and the claw portions 320 and 330 constitute an example of the “convex portion” according to the present invention, and the groove portion 350 forms an example of the “concave portion” according to the present invention. The plate 610 is elastic. It is made of an elastic member such as a high metal or resin, and has an engaging portion 612 formed so as to protrude from the plate main body portion 611 toward the direction in which the cover 710 is arranged (that is, the Z direction in FIG. 6). ing.

  The engaging portion 612 includes a hook portion 210. The hook portion 210 is provided so as to surround the claw portions 320 and 330 when viewed from the outer surface side of the side portion of the cover main body portion 711 (that is, when viewed from the direction of the arrow X in FIG. 5). When the hook portion 210 is fitted into the groove portion 350 and hooked on the claw portions 210 and 220, the engaging portion 612 and the engaging portion 712 are engaged. When engaged in this way, the hook portion 210 is inserted along the bottom surface of the groove portion 350 extending in the Z direction. In addition, the hook portions 210 are provided on both sides of the front surface of the mounting case 810 (see FIG. 5), and are arranged so as to sandwich the cover main body portion 711 from both sides of the front surface when engaged as described above.

  In FIG. 7, particularly in the present embodiment, the engaging portion 612 includes a spring portion 220 that can exhibit an elastic force along the Y direction as an example of the “first direction” according to the present invention. The spring portion 220 is an example of the “elastic portion” according to the present invention, and constitutes an example of the “positioning means” according to the present invention together with the hook portion 211, the convex portion 311a, and the claw portion 330. The spring part 220 is formed integrally with a plate body part 611 made of an elastic member. When the engaging portion 612 and the engaging portion 712 (see FIG. 6) are engaged with each other, the spring portion 220 is brought into contact with the claw portion 330 so as to exert an elastic force along the Y direction, and the hook portion. A hook portion 211 which is a part of 210 is configured to be pressed against the convex portion 311a. Therefore, the position in the Y direction of the hook part 210 with respect to the cover main body part 711 can be stabilized with reference to the edge P1 of the convex part 311a (in other words, the edge of the groove part 350). That is, it occurs due to manufacturing tolerances for enabling the engaging portion 612 and the engaging portion 712 (more specifically, the hook portion 210 and the groove portion 350, and the claw portions 320 and 330) to be engaged with each other. As a result, it is possible to almost eliminate the displacement of the relative positional relationship between the cover 710 and the plate 610 in the Y direction. In other words, it is possible to eliminate almost no backlash when the hook portion 210 is hooked on the claw portions 320 and 330 while being fitted to the groove portion 350. Therefore, for example, it is possible to reduce the displacement of the position of the window portion 615 opened in the plate 610 along the Y direction with respect to the pixel region 10a of the electro-optical device 500 fixed to the cover 710. In other words, the positional relationship between the pixel region 10a of the electro-optical device 500 (and the window 625 of the cover 710) and the window 615 of the plate 610 can be stabilized. Accordingly, when the electro-optical device 500 accommodated in the mounting case 810 is mounted as the light valves 100R, 100G, and 100B in the liquid crystal projector 1100 described above with reference to FIG. 1, for example, the cover 710, the plate 610, and the like Since the relative positional relationship in the Y direction of the electro-optical device 500 is deviated, for example, it is possible to reduce that the light is blocked more than necessary by the cover 710 or the plate 610 or that light leakage occurs. . As a result, a high-quality image can be displayed by the electro-optical device 500 accommodated in the mounting case.

  Further, in FIGS. 6 and 7, particularly in the present embodiment, the claw portions 320 and 330 are formed to extend in the Z direction as an example of the “second direction” according to the present invention that intersects the Y direction on the side surface. The lengths extending in the Z direction are different from each other. Further, the claw portions 320 and 330 are arranged so that one ends thereof are aligned with each other on the side different from the plate body portion 611 side in the Z direction. Therefore, by hooking the hook portion 210 to the one end of the claw portions 320 and 330, it is possible to reliably reduce the displacement of the plate 610 toward the plate main body portion 611 with respect to the cover 710.

  In addition, in FIGS. 6 and 7, in the present embodiment, the spring portion 220 is in contact with the claw portion 330 having a longer length along the Z direction among the claw portions 320 and 330. In other words, of the claw portions 320 and 330, the length along the Z direction of the claw portion 320 on which the spring portion 220 is not abutted is along the Z direction of the claw portion 330 on which the spring portion 220 is abutted. Short compared to the length. Therefore, when the hook part 210 is inserted along the bottom surface of the groove part 350 extending in the Z direction in order to engage the engaging part 612 and the engaging part 712, the hook part 210 is brought into contact with the spring part 220. It can reduce that it deform | transforms toward the outer surface side (namely, the side away from the side surface of the cover main-body part 611) by the nail | claw part 330 which is not performed. Further, with the deformation of the hook portion 210, the spring portion 220 is also deformed to the outer surface side. For example, the spring portion 220 rides on the claw portion 330, and the spring portion 220 comes into contact with the claw portion 330. Occurrence of a situation that disappears can be reduced.

  In the present embodiment, in particular, the spring part 220 is formed at a position corresponding to between the claw part 320 and the claw part 330, so that the spring part 220 and the claw part 320 or 330 overlap each other on the side surface. Can be reduced. Therefore, when the said spring part 220 overlaps with the said nail | claw part 320 or 330, it can reduce that the said spring part 220 deform | transforms toward an outer surface side. Therefore, it can suppress that the elastic force by the spring part 220 reduces.

  Further, as shown in FIG. 7, in the present embodiment, in particular, the claw portion 330 includes a support portion 332 extending in the Z direction with a substantially constant width, and a tapered portion 331 extending from the support portion 332 toward the plate body portion 611. And have. The tapered portion 331 is formed so that the width W1 gradually becomes narrower as it approaches the plate body 611 side. Therefore, the spring portion 220 can be easily inserted from the plate main body portion 611 side along the tapered portion 331, and the elastic force along the Y direction by the spring portion 220 can be surely exhibited by the support portion 332. . The support portion 330 also has a function of supporting the hook portion 210 so as not to be displaced toward the plate body portion 611 along the Z direction.

  In addition, as shown in FIGS. 7 and 8, particularly in the present embodiment, the tapered portion 331 is formed such that the thickness T1 gradually decreases as it approaches the plate body 611 side. The claw portion 320 has a support portion 322 extending in the Z direction with a substantially constant width, and a tapered portion 321 extending from the support portion 322 toward the plate body 611 side. The tapered portion 321 is formed so that its thickness gradually decreases as it approaches the plate main body portion 611 side, in the same manner as the tapered portion 331. Therefore, when engaging the engaging portion 612 and the engaging portion 712, the hook portion 210 can be easily disposed so as to surround the claw portions 320 and 330. That is, the hook part 210 can be easily inserted from the plate body part 611 side along the surfaces of the taper parts 321 and 331. That is, it can reduce that the insertion of the hook part 210 is prevented by the thickness of the taper parts 321 and 331 on the plate body part 611 side.

  As described above, according to the mounting case 810 according to the present embodiment, the relative positional relationship between the mounting case 810 and the electro-optical device 500 can be reduced. As a result, a high-quality image can be displayed by the electro-optical device 500 accommodated in the mounting case 810.

In this embodiment, the spring portion 220 is provided on the plate 610. However, compared with the case where the spring portion 220 is not provided on the plate 610, the manufacturing process for manufacturing the mounting case is hardly complicated. I will not invite you at all. For this reason, the increase in the manufacturing cost for manufacturing a mounting case is hardly caused. Further, even in the process of housing the electro-optical device in the mounting case, the number of steps is hardly increased compared to the case where the spring portion 220 is not provided on the plate 610.
