Abstract
A sealing material is formed to cover a drain driver comprising a horizontal shift register and a sampling portion and its edge lines are linear on the horizontal shift register. Operation characteristics of TFT elements just below the sealing material are changed and are different from those of TFT elements of the area not below the sealing material. However, operation characteristics do not differ between phases of the shift register, and adverse effects for display can be prevented.
