(Embodiment 1)
In the present embodiment, the configuration of the semiconductor device according to one aspect of the present invention will be described with reference to the drawings.

1 (A) and 1 (B) are views illustrating the semiconductor device of one aspect of the present invention, with reference to FIG. 1 (A).
) Will be used to explain the folded form.

The semiconductor device 100 has a display unit 101. The display unit 101 can be folded. The semiconductor device 100 has a first housing 111 that holds the display unit 101 and a second housing 112. In the first housing 111, since the display unit 101 is folded, the second housing 111 is second.
Can be in contact with the housing 112 of. In order to maintain the folded form, the first housing 1
In the first region 102 where 11 and the second housing are in contact with each other, the first housing 111 has a first fitting portion 113, and the second housing 112 has a second fitting portion. Has 114. Further, in the second region 122 where the first housing 111 and the second housing are in contact with each other, the first housing 111 has a third fitting portion 123, and the second housing 112 has a second housing 112. It has a fourth fitting portion 124. For example, the first
The fitting portion 113 and the second fitting portion 114 can be configured by a hook portion having a claw portion such as a side release buckle or a front release buckle. Third fitting portion 123 and fourth
The fitting portion 124 of the above can be configured by a side release buckle, a front release buckle, or the like. In this case, the first fitting portion 113 or the third fitting portion 123 is used as a socket (claw concave portion), and the second fitting portion 114 or the fourth fitting portion 124 is used as a plug (claw convex portion). It is good to say.

The display unit 101 can be used even in the folded form. Therefore, the display unit 1
Fold it so that part of 01 faces up. In this state, the first housing 111 and the display unit 101
In the region 118 where the above overlaps, the first housing 111 has a transparent region 111a. The display unit 101 can be in contact with the transparent region 111a. The transparent area 111a is the display unit 101.
However, it may not be present on the entire surface, and may have the shape of a frame.

In order for a part of the display unit 101 to face the front, for example, the display unit 101 may have an even number of bent regions and may be folded so that the bent directions of the bent regions are opposite to each other. FIG. 1 (A)
Has two bent regions (128, 129), and shows a form in which a part of the display unit 101 faces up. If the bending direction of the region 128 is opposite to that of the region 129, that is, if the region 128 is a mountain fold, the region 129 is a valley fold. In the bent region, in the case of an active type panel, the display unit 101 preferably has a radius of curvature of 4 mm or more in consideration of the bending strength of the transistor. Of course, the flexible display unit 101 can have a curved surface other than the bent region.

The internal thickness 119 of the semiconductor device 100 formed by the first housing 111 and the second housing 112 has two to five times the radius of curvature of the display unit 101. The first housing 111 and the second housing 112 may have a curved surface that matches the curvature of the display unit 101. Thereby, the first
The space between the housing 111 or the second housing 112 and the display unit 101 can be reduced. As a result, the thickness 120 of the semiconductor device 100 can be further reduced. The thickness 120 is preferably twice or less the internal thickness 119 in consideration of the sophistication of the design.

FIG. 1B shows how the display unit 101 is unfolded from the folded state. The first fitting portion 113 to the fourth fitting portion 124 are put into a non-fitting state, and the first housing 111 is separated from the second housing 112. A part of the display unit 101 is fixed to a region including the transparent region 111a of the first housing 111, and the other part of the display unit 101 is fixed to a part of the second housing 112.

2A and 2B show a state in which the display unit 101 is expanded. FIG. 2A is a cross-sectional view, and FIG. 2B is a top view. As shown in FIGS. 2A and 2B, the display unit 101 has a region 146 that overlaps with the first housing 111, a region 148 that overlaps with the second housing 112, and a region 147 that does not overlap with any of the second housing 112. Since the area 147 does not come into contact with any of the housings, the area 146,
Higher flexibility than 148. The area 147 can have a larger area than the area 146. The area 147 can have a larger area than the area 148.

The area 146 becomes a displayable area when the display unit 101 is folded as shown in FIG. 1 (A). Therefore, the area 146 can have a larger area than the area 148.

When the visibility of the display unit 101 is made equal between such areas 146 to 148, FIG.
As shown in (A), the back side of the display unit 101 (the surface of the display unit 101 in contact with the housing 112).
A black film 145 is placed on the surface. The film 145 has an organic material and has a display unit 101.
Use a thinner film than. As a result, it is possible to bend following the display unit 101. The film 145 is preferably made of a material having high strength and a high elastic modulus so as to withstand repeated bending and stretching and twisting, because it also serves as reinforcement. Based on these, examples of the material of the film 145 include super fibers such as aramid type and polyarylate type.

As shown in FIG. 2B, by having the first housing 111 and the second housing 112, the expanded display unit 101 can be used. Of course, the display unit 101 may be used by holding only the first housing 111. Further, the display unit 101 may be used by holding only the second housing 112.

Since the first housing 111 serves as a handle, the hardness may be changed to make it easier to grip. The region 111b of the first housing 111, which corresponds to the side surface of the semiconductor device 100, may have a material that is harder than the other regions, while the other regions may have a soft material. Second housing 1
Similarly in 12, the region 112a corresponding to the side surface of the semiconductor device 100 may have a harder material than the other regions, while the other regions may have a soft material.

The first housing 111 may include an input device. The second housing 112 may include an input device.

When the third fitting portion 123 and the fourth fitting portion 124 overlap with the display portion 101 and the visibility is reduced, the third fitting portion 123 and the fourth fitting portion 124 have translucency. It is good to have the material to have. Further, as shown in FIG. 2B, it is preferable that these fitting portions are arranged at the end portions of the display unit 101 in consideration of visibility, but they may be arranged up to the central portion of the display unit 101. On the other hand, the first fitting portion 113 and the second fitting portion 114 may be of a form in which the housing 111 and the housing 112 can be fitted and detached.

When the area from the fitting portion 114 to the region 112a corresponding to the side surface of the semiconductor device 100 is composed of a translucent portion, the region where the display can be confirmed in the folded state of the display unit 101 becomes large, which is preferable. The display unit 101 corresponding to this area may be used to receive a simple signal (presence or absence of mail or incoming call) such as blinking / lighting of a lamp.

If the display unit 101 is a dual emission type, the first fitting unit 113
It is preferable that the portion of the housing 111 that is adhered to the second fitting portion 114 and the display portion 101 also has translucency. In this case, the film 145 is translucent. Housing 111 and housing 112
May have translucency.

The bent region 129 is provided between the region 146 and the region 147, and the bent region 128 is provided between the region 147 and the region 148.

In addition, a touch panel may be mounted as an input device arranged so as to overlap the display unit 101. Examples of the touch panel include an optical touch panel and a capacitive touch panel. An optical touch panel is preferable because the display unit 101 is highly flexible.

In this way, a foldable device can be provided.

As shown in FIG. 3, the first cushioning material 131 may be arranged between the first housing 111 and the display unit 101. Similarly, the second cushioning material 132 is used in the second housing 112 and the display unit 101.
It may be placed between and. The first housing 111 and the second housing 112 have a material that is harder than the display unit 101 in order to hold the display unit 101. When the first housing 111 and the display unit 101 and the second housing 112 and the display unit 101 come into contact with each other in the folded state of the display unit 101,
The display unit 101 is susceptible to impact. Therefore, as shown in FIG. 3, the first cushioning material 13
The impact on the display unit 101 can be softened by the first and second cushioning materials 132.

FIG. 4A shows a semiconductor device 100 provided with an external circuit region 150. The display unit 101 having a pixel unit may have a scanning line drive circuit or a signal line drive circuit on the same surface as the pixel unit. However, since the display unit 101 has the bent regions 128 and 129, the scanning line drive circuit and the signal line drive circuit may be provided in the external circuit region 150. That is, the external circuit area 150 is provided with a circuit unit. As a result of providing the circuit unit in the external circuit area 150, the flexibility of the display unit 101 can be increased. The wiring of the display unit 101 can be electrically connected to the drive circuit of the external circuit area 150 via a flexible printed circuit board (FPC, not shown). In order to maintain the miniaturization of the semiconductor device 100, the external circuit area 150 is
It is preferable to arrange it so as to overlap with the display unit 101. For example, it can be arranged outside the second housing 112. In addition to the drive circuit, a battery or the like may be arranged in the external circuit area 150.

FIG. 4B shows a semiconductor device provided with external circuit regions 150a and 150b. Figure 4 (
The location of the external circuit area 150 is different from that of A). The external circuit area 150a may be provided in contact with the first housing 111, and the external circuit area 150b may be provided in contact with the second housing 112. From FIG. 4A, the thickness of the entire semiconductor device 100 can be reduced.

In this way, a foldable semiconductor device can be provided.
