<First Embodiment>
FIG. 1 is a plan view schematically showing a liquid crystal display device as an electro-optical device. Reference numeral 10 in FIG. 1 denotes a liquid crystal display device (electro-optical device). The liquid crystal display device 10 is used as a liquid crystal module. As shown in FIG. 2 which is a cross-sectional view taken along the line B-B in FIG. 1, a liquid crystal panel 11, a plastic frame 12 (support member), A metal frame 15 including a frame 13 and an upper frame 14 is provided.

The liquid crystal panel 11 includes a liquid crystal panel body 16, a diffusion sheet 17, a prism sheet 18, a light guide plate 19, a reflection sheet 20, a light source (not shown), and the like, and introduces light from the light source into the liquid crystal panel body 16. 16 is configured to display a desired display.
The liquid crystal panel main body 16 includes a pair of opposing substrates 21 and 22, and a liquid crystal layer (not shown) is sealed between the substrates 21 and 22. Pixel electrodes, TFTs, wirings, and the like are formed on the inner surface side (liquid crystal layer side) of one substrate 21, and color filters, common electrodes, and wirings are formed on the inner surface side (liquid crystal layer side) of the other substrate 22. Etc. are formed. A polarizing plate 23 is attached to the outer surface of each of the substrates 21 and 22.

Although not shown, an external connection substrate such as an FPC is connected to the peripheral portion of the liquid crystal panel body 16 to an extended portion formed by extending the substrate 21 of the liquid crystal panel body 16. In addition, a driving IC (not shown) is provided in the extending portion, and the TFT and the like of the substrate 21 are driven by this driving IC.
The liquid crystal panel 11 having such a configuration has an outer surface side of the substrate 22 as a display surface, and a rectangular display area A is formed at the center of the display surface as shown in FIG. .

  Further, the liquid crystal panel 11 is accommodated in the plastic frame 12 as shown in FIG. 2, whereby the side surface and the bottom surface side are supported by the plastic frame 12. The plastic frame 12 has a rectangular frame shape made of a resin such as polycarbonate, and includes a rectangular annular bottom plate 12a and side plates 12b rising from the outer sides of the bottom plate 12a. As shown in FIG. 3 which is a plan view of the plastic frame 12, in this embodiment, two contact pieces 24 are formed on each of the four side plates 12b.

As shown in FIG. 2, these contact pieces 24 are formed so as to protrude outward from the upper end portion of the side plate 12b, that is, are formed of protruding portions, which are contact portions in the present invention. Thus, the tip is designed so as to contact the side plate of the upper frame 14.
A fitting projection 25 is also formed below the contact piece 24 so as to protrude outward from the side plate 12b. In the present embodiment, a total of eight fitting protrusions 25 are formed, two for each side plate 12b, like the contact piece 24. However, the number, the formation position, and the shape of the contact pieces 24 and the fitting protrusions 25 are not limited to those shown in FIGS. 2 and 3 and can be arbitrarily designed.
In the present embodiment, since the plastic frame 12 made of resin is used as the support member in the present invention, the contact piece 24 and the fitting projection 25 can be integrally formed with the bottom plate 12a and the side plate 12b. It has become easier.

The metal frame 15 is composed of the lower frame 13 and the upper frame 14 as described above, and the bottom surface side and the top surface side of the liquid crystal panel 11 in a state in which these are fitted and fixed as shown in FIG. (Display surface side). The lower frame 13 and the upper frame 14 constituting the metal frame 15 are both made of a metal material such as stainless steel, that is, a conductive material.
The lower frame 13 includes a rectangular annular bottom plate 13a and a side plate 13b rising from each outer side of the bottom plate 13a. It is to hold. The lower frame 13 is formed such that the height of the side plate 13b is lower than the position of the contact piece 24 of the plastic frame 12. Thereby, the side plate 13b of the lower frame 13 does not interfere with the contact piece 24, and therefore, the contact piece 24 can come into contact with the side plate of the upper frame 14.

  The side plate 13b is formed with a fitting recess 26 at a position corresponding to the fitting protrusion 25 of the plastic frame 12. That is, a total of eight of these fitting recesses 26 are formed, two for each side plate 13b. Each of the fitting recesses 26 is configured to be fitted with the corresponding fitting protrusion 25, and is formed by a through hole or a hole recessed on the inner surface side of the side plate 13b. Under such a configuration, the plastic frame 12 is incorporated and accommodated in the lower frame 13 in a state in which the liquid crystal panel 11 is accommodated, and the lower frame 13 is fitted by the fitting protrusion 25 and the fitting recess 26. It is fixed to.

Further, on the outer surface of the side plate 13b, there are two fitting holes 27 that fit into fitting projections of the upper frame 14 to be described later, like the fitting recess 26, two for each side plate 13b. Is formed.
Although not shown, the lower frame 12 is electrically connected to a ground potential portion provided in the liquid crystal panel 11 via a ground wiring or the like, whereby the lower frame 12 itself is also grounded. .

  The upper frame 14 includes a rectangular annular upper plate 14a and a side plate 14b descending from each outer side of the upper plate 14a. The display area A of the display panel 11 is exposed on the upper plate 14a. An opening 28 is formed. The opening 28 is formed to be slightly larger than the display area A, and thereby the display area A is surely exposed. With this configuration, the upper frame 14 holds the display side of the display panel 11 without covering the display area A. The upper frame 14 is formed so that the side plate 14 covers substantially the entire area of the outer surface side of the side plate 12 a of the plastic frame 12 and the outer surface side of the side plate 13 a of the lower frame 13.

Thereby, the side plate 12a of the plastic frame 12, the side plate 13b of the lower frame 13, and the side plate 14b of the upper frame 14 have an overlapping region F that overlaps mostly on the outside of the side surface of the liquid crystal panel 11. It has become.
The contact piece 24 of the plastic frame 12 is abutted and brought into contact with the inner surface of the side plate 14b of the upper frame 14 on the upper plate 14a side.

  Further, on the inner surface of the side plate 14b, fitting convex portions 29 are formed at positions corresponding to the fitting holes 27 of the lower frame 13, respectively. That is, a total of eight of these fitting convex portions 29 are formed, two for each side plate 14b. These fitting projections 29 are configured so as to be fitted (engaged) with the corresponding fitting holes 27, and for example, punching (pressing) so that the side plate 14b bulges to the inner surface side thereof. As a result, it is formed. Under such a configuration, the lower frame 13 is incorporated (fitted) and accommodated in the upper frame 14, and is fitted into the upper frame 14 by fitting the fitting hole 27 and the fitting convex portion 29. It is fixed. In addition, the said fitting hole 27 and the fitting convex part 29 function also as an electroconductive part which conducts the lower frame 13 and the upper frame 14 in this invention.

Under such a configuration, the metal frame 15 has the upper frame 14 fitted to the lower frame 13 from the display surface side of the liquid crystal panel 11, and the liquid crystal panel 11 is accommodated therein via the plastic frame 12. It has become a thing.
Here, in the liquid crystal display device 10 (liquid crystal module), the tolerance when the liquid crystal panel body 16 (liquid crystal panel 11) having the display area A is incorporated in the plastic frame 12 is the same as the conventional structure shown in FIG. G1 is necessary in the design. Further, as shown in FIG. 2, when the plastic frame 12 is assembled into the metal frame 15, a tolerance G4 is required at a position where the tip of the contact piece 24 contacts the inner surface of the side plate 14b of the upper frame 14. . That is, by design, the tip of the contact piece 24 is in contact with the inner surface of the side plate 14b of the upper frame 14, but when the contact piece 24 is formed to extend excessively to the side plate 14b side, There is a possibility that the plastic frame 12 may not fit in the upper frame 14 (gold frame 15). Therefore, a design tolerance G4 is necessary to provide a certain amount of clearance.
Here, in order to explain the tolerance G4, FIG. 2 shows a large distance between the tip of the contact piece 24 and the inner surface of the side plate 14b of the upper frame 14. (The same applies to FIGS. 4, 5, and 6 below).

  The lower frame 13 has a side plate 13b disposed between the side plate 12b of the plastic frame 12 and the side plate 14b of the upper frame 14, with a fitting recess 26 in the plastic frame 12 and a fitting hole 27 in the upper frame 15. By being fitted to each other, they are fixed between the plastic frame 12 and the upper frame 15. At that time, unlike the conventional case, the tolerance between the side plate 12b of the plastic frame 12 and the side plate 13b of the lower frame 13 and between the side plate 13b of the lower frame 13 and the side plate 14b of the upper frame 14 is the above-mentioned tolerance G4. Since it is absorbed, it becomes unnecessary in design.

  Therefore, according to the liquid crystal display device 10 (liquid crystal module) of the present embodiment, the abutment piece 24 is provided on the plastic frame 12 and is designed to abut on the side plate 14 b of the upper frame 14. As described above, the distance D for determining the display position of the display area A of the liquid crystal panel 11, that is, the distance D between the outer surface of the side plate 14 b of the upper frame 14 positioned outside the metal frame 15 and the edge E of the display area A is given. The two assembly tolerances of the tolerance G1 and the tolerance G4 are not included. Therefore, since there are two tolerances that existed in the past, the positional accuracy of the display area A can be improved accordingly.

Further, since the contact pieces 24 of the plastic frame 12 are provided so as to correspond to the outer sides of all the side surfaces of the liquid crystal panel 11, the positional accuracy of the display region A is improved in all the side surface directions of the liquid crystal panel 11. be able to.
Further, in the metal frame 15, the side plate 14 b of the upper frame 14 is disposed outside the side plate 13 b of the lower frame 13, so that the upper frame 14 and the plastic frame 12 are directly contacted by the contact piece 24. Therefore, the position of the opening 28 of the upper plate 14a with respect to the display area A of the liquid crystal panel 11 can be determined (defined) with higher accuracy. Further, since the upper plate 14a of the upper frame 14 can cover the upper end of the side plate 12b of the plastic frame 12 and the upper end of the side plate 13b of the lower frame 13, it is possible to prevent foreign matter and the like from entering between these side plates.

  Further, the lower frame 13 and the upper frame 14 are formed of a conductive material, the lower frame 12 is grounded via the ground wiring as described above, and the lower frame 13 and the upper frame 14 function as conductive portions. Since the fitting hole 27 and the fitting projection 29 are connected to each other, electrical noise such as static electricity generated in the liquid crystal panel 11 or the like is shielded in the metal frame 15 so as not to go outside. Can do.

Second Embodiment
Next, a second embodiment of the electro-optical device of the invention will be described.

A contact piece 42 made of the protruding portion is formed. The contact piece 42 is designed to contact the inner surface of the side plate 14b of the upper frame 14 in the same manner as the contact piece 24 in the liquid crystal display device 10 of FIG.

Further, in the lower frame 13, a fitting recess 26 formed in the side plate 13 b is formed by a through-hole penetrating the front and back of the side plate 13 b in this embodiment.
With such a configuration, when the plastic frame 41 is assembled in the lower frame 13, the contact piece 42 of the present embodiment is fitted into the fitting recess 26 and penetrates through the fitting recess 26. When the lower frame 13 is assembled in the upper frame 14 in this state, the contact piece 42 that penetrates the fitting recess 26 comes into contact with the inner surface of the side plate 14b of the upper frame 14 as described above. Yes.

Therefore, even in the liquid crystal display device 40, the contact piece 42 is provided on the plastic frame 41 and is designed to contact the inner surface of the side plate 14b of the upper frame 14. The interval D for determining the display position of the area A does not include two assembly tolerances of the tolerance G1 and the tolerance G4. Therefore, since there are two tolerances that existed in the past, the positional accuracy of the display area A can be improved accordingly.
In addition, since the contact piece 42 penetrates the fitting recess 26 of the side plate 13b of the lower frame 13 and contacts the side plate 14b of the upper frame 14, the lower frame 13 is securely attached to the plastic frame 41. Can be fixed to.

That is, the inner surface (contact portion) 53a of the bent portion 53 and the outer surface of the upper end portion of the side plate 51b are designed to contact each other.

Here, the bent portion 53 is formed over the entire circumference of the rectangular frame shape in the present embodiment, and therefore the bent portion 53 also functions as a reinforcing portion that improves the strength of the upper frame 52. It is supposed to be.

The interval D for determining the display position of the display area A includes the above-described tolerance G1 and the tolerance G4 between the inner surface (contact portion) 53a of the bent portion 53 and the side plate 51b of the plastic frame 51. Two assembly tolerances will not be included. Therefore, even in the liquid crystal display device 50 of the present embodiment, since there are two tolerances that existed in the past, the positional accuracy of the display area A can be improved accordingly.
Further, as described above, the bent portion 53 serving as the contact portion can function as a reinforcing portion that improves the strength of the upper frame 52, and thus the strength of the entire metal frame can be improved.

The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention.
