Title:
DISPLAY DEVICE, AND METHOD FOR MANUFACTURING THE SAME
Document Type and Number:
Japanese Patent JP2011029579
Kind Code:
A
Abstract:

To solve the problem that as the number of pixels is increased with an increase in the definition of a display device and thus the numbers of gate lines and signal lines are increased, it becomes difficult to mount an IC chip having a driver circuit for driving the gate line and the signal line by bonding or the like to cause an increase in manufacturing costs.

A pixel portion and a driver circuit driving the pixel portion are provided on the same substrate. A thin film transistor in which an oxide semiconductor is used is used for the pixel portion, and at least a part of the driver circuit is formed using a thin film transistor in which an oxide semiconductor is used. Both the pixel portion and the driver circuit are provided on the same substrate, whereby manufacturing costs are reduced.
