    • PROBLEM TO BE SOLVED: To provide a highly efficient and low cost switching power supply.SOLUTION: An inverter includes high voltage resistant transistors 1, 3, 5, 7 and low voltage resistant transistors 2, 4, 6, 8. The transistors 1-8 respectively include parasitic diodes 1a-8a. For example, when a current is made to flow from an output node N1 to an output terminal 22, the low voltage resistant transistor 2 is switched off, whereas the high voltage resistant transistor 1 is switched on by means of a power supply which applies a higher voltage than the voltage of the output node N1 to the gate of the high voltage resistant transistor 1. Because a current hardly flows in the parasitic diode 1a of the high voltage resistant transistor 1, a recovery current of the high voltage resistant transistor 1 is small.
    • 要解决的问题:提供高效且低成本的开关电源。解决方案:逆变器包括耐高压晶体管1,3,5,7和耐低压晶体管2,4,6,8。晶体管1- 8分别包括寄生二极管1a-8a。 例如,当使电流从输出节点N1流向输出端子22时,低电压晶体管2被断开,而耐高压晶体管1通过施加电压的电源来接通 电压高于输出节点N1的电压到高耐压晶体管1的栅极。由于电流几乎不流过耐高压晶体管1的寄生二极管1a,所以耐高压晶体管1的恢复电流为 小。

    • PROBLEM TO BE SOLVED: To provide a semiconductor device with a small variation in characteristics.SOLUTION: A semiconductor device includes a first switching element (a high-withstand-voltage transistor Q1) and a second switching element (a resistive element R1 and a low-withstand-voltage transistor Q2) that are connected in series between nodes N1 and N2, and a third switching element (a low-withstand-voltage transistor Q3) that is connected in parallel to the second switching element. When the transistor Q2 is turned on, the transistor Q1 turns on, and then when the transistor Q3 is turned on, a conductive state is established between the nodes N1 and N2. As a result, the first switching element having a high on-resistance value is turned on, and then the high-withstand-voltage transistor Q1 is turned on, thereby reducing the variation in turn-on time.

    • PROBLEM TO BE SOLVED: To provide a semiconductor device capable of preventing storage information from being lost by incidence of light. SOLUTION: Advancing directions of the lights are aligned to be directed to a normal direction of a lower side optical sheet 7 by the optical sheet 7, when the lights having the random advancing directions are get incident to the optical sheet 7 from a backlight module or a display element. The almost all lights emitted from a prism face of the lower side optical sheet 7 are thereby emitted within a range of a fixed emission angle ±θ° with respect to the normal of the lower side optical sheet 7, and are shielded surely by a lower side light shielding body 5, not to get incident turning in around an peripheral edge of the lower side light shielding body 5. Incident lights into an information storage holding part 3 are effectively reduced thereby, and the storage information is prevented from being lost out of the information storage holding part 3. Advancing directions of the incident lights are aligned to be directed to a normal direction of an upper side optical sheet 8 by the optical sheet 8, as to an upper side light shielding body 6 and the upper side optical sheet 8, and the lights are shielded surely by the upper side light shielding body 6.
