An electronic component or display device of the present invention can be provided by using a following pattern formation method. The soy protein product is obtained by extracting a soy protein source material with an aqueous calcium salt solution to form an aqueous soy protein solution, separating the aqueous soy protein solution from residual soy protein source, adjusting the pH of the aqueous soy protein solution to a pH of about 1. The roll-formed steel profile can form a first wall portion and two projecting wall portions that extend from the first wall portion in a generally perpendicular manner. If the receiver determines not to demodulate the enhancement layer, the receiver can power down the enhancement layer demodulator, or otherwise minimize the power expended in the enhancement layer demodulator.
