Conductive layers having knots are adjacently formed with uniform distance therebetween. Droplets of the conductive layers are discharged to stagger centers of the droplets in a length direction of wirings so that the centers of the discharged droplets are not on the same line in a line width direction between the adjacent conductive layers. Since the centers of the droplets are staggered, parts of the conductive layers each having a widest line width (the widest width of knot) are not connected to each other, and the conductive layers can be formed adjacently with a shorter distance therebetween.

2. Description of the Related Art
In the accompanying drawings:
FIGS. 1A to 1C are schematic views of the present invention;
FIGS. 2A to 2C show a method of manufacturing a display device of the present invention;
Embodiment mode of the invention will be described in detail with reference to the drawings. However, it is easily understood by those skilled in the art that the invention is not limited by the following descriptions and various changes may be made in forms and details without departing from the spirit and the scope of the invention. Therefore, the invention should not be limited to descriptions of Embodiment modes below. The same reference numerals are commonly given to the same components or components having the same function in the structure of the invention, and a repetitive explanation will be omitted.
Embodiment Mode 1 of the present invention will be described with reference to FIGS. 1A to 1C.
One feature of the present invention is that at least one or more of components required to manufacture a semiconductor device or a display device, such as a conductive layer for forming a wiring layer or an electrode, or a mask layer for forming a predetermined pattern, is/are formed by a method capable of selectively forming a pattern into a desired shape to manufacture a semiconductor device or a display device. In the present invention, a component (also referred to as a pattern) refers to a conductive layer such as a wiring layer, a gate electrode layer, a source electrode layer, or a drain electrode layer; a semiconductor layer; a mask layer; an insulating layer; or the like, which is included in a thin film transistor or a display device, and includes all components that are formed to have a predetermined shape. A droplet discharge (ejection) method (also referred to as an ink-jet method, depending on its mode), that can form a conductive layer, an insulating layer, or the like into a predetermined pattern by selectively discharging (ejecting) a droplet of a composition mixed for a particular purpose, is employed as the method capable of selectively forming a substance to be formed into a desired pattern. In addition, a method capable of transferring or drawing a component into a desired pattern, for example, various printing methods (a method of forming a substance to be formed into the desired pattern, such as screen (mimeograph) printing, offset (planograph) printing, relief printing, gravure (intaglio) printing, or the like), a dispenser method, a selective-coating method, or the like can also be employed.
