，この状態でＴＶを見ることができる。The difference between this embodiment and the previous embodiment is that the fourth embodiment is different from the fourth embodiment.
As is clear from the figure, the joint 20d is on the front side of the CASE 20, so in the folded state, the LCDE 15
a. 15b were on the inside facing each other, so I couldn't watch TV when folded.
In this embodiment, since the joint portion 20d is on the back side of the CASE 20, the LCDEs 15a and 15b are
are on the outside of each other, so even in the folded state, the LCDE 15a. 15b faces outward, and you can watch TV in this state.
したがって，ＳＷ１９ａをＯＮにすると，このように折
りたたんだ状態でもＴＶを見ることができ，スペースが
ないときや電車内で立って見るときなどに好適である。Therefore, when the SW 19a is turned on, the TV can be watched even in the folded state, which is suitable when there is no space or when watching while standing on a train.

いてもよい。In the above embodiment, an example was shown in which each LCDE was provided with a backlight using a fluorescent lamp, but as shown in Fig. 13, it is possible to efficiently collect natural light and indoor light and use it as a backlight. You may also do so. In other words, in this type of conventional device, the mirror was fixed to the rear case, making it impossible to efficiently collect light. However, in this embodiment, the case 50 consists of a front case 51 for mounting the LCDE 54, a mirror section 52 having a flexible constriction section 55, and a rear case 53 for lowering the center of gravity to stabilize and fix the device. , the angle of the front case 51 and the mirror part 52 can be freely changed independently with respect to the rear case 53, and the vertical angle can be adjusted. It can be rotated freely in either direction, and light can be focused and efficiently irradiated onto the LCDE 54 regardless of the incident angle (direction) of ambient light and the position of the device, resulting in a bright and easy-to-read display device. This can be achieved without using electrical energy, resulting in power savings. Further, as the mirror of the mirror portion 52, ground glass may be used in order to reduce unevenness in the strength of the incident light, and a concave mirror may also be used.
