A light-emitting device () includes a first light-emitting region () and a second light-emitting region (). The first light-emitting region () emits a light ray having a first color by making a first light-emitting layer group including at least two or more kinds of light-emitting layers emit light. In addition, the second light-emitting region () emits a light ray having the first color (for example, daylight color, natural white color, white color, warm white color, or incandescent color) by making a second light-emitting layer group including at least two or more kinds of light-emitting layers emit light. In addition, at least one kind of light-emitting layer included in the second light-emitting layer group emits a light ray having a different spectrum peak from all of the light-emitting layers included in the first light-emitting layer group. Therefore, the color-rendering properties of light emitted from the light-emitting device () are improved.

A supporting unit in a moving table device, easily connected to a base and a table, is provided. A supporting unit (U&#x3b1;) has a pair of planar bearing plates. Inside the planar bearing plates are positioned spherical bearing plates, respectively. Further, a spherical axial member is sandwiched between the spherical bearing plates (). A planar bearing is formed between each of the planar bearing plates and each of the spherical bearing plates. A spherical bearing is formed between each of the spherical bearing plates and the spherical axial member. Thus, the supporting unit (U&#x3b1;) is provided with a certain degree of movability in five-axis directions. With the high degree of movability, the supporting unit (U&#x3b1;) can be easily connected to a base and a table.
