Embodiment approach 1
[0070] Refer below Figure 1A to 3 The structure of a display device according to a preferred embodiment of the present invention is described. The display device of the present invention includes a plurality of pixels 10, and each pixel intersects each other at the source line Sx (x is a natural number and satisfies 1≤x≤m) and the gate line Gy (y is a natural number and satisfies 1≤y≤n). And the area between the insulators includes multiple elements (see Figure 1A ). The pixel 10 includes a light-emitting element 13, a capacitor 16, and two transistors. One of the two transistors is a switching transistor 11 (hereinafter also referred to as TFT 11), which is used to control the video signal input to the pixel 10; the other is a driving transistor 12 (hereinafter also referred to as TFT 12), which is used to control light emission Element 13 emits light / no light. Both TFTs 11 and 12 are field effect transistors, which have three terminals of a gate, a source, and a drain.

Embodiment approach 2
[0098]The above structure is applicable to the case where the TFT 12 is a P-channel TFT. In this embodiment mode, a case where the TFT 12 is an N-channel TFT will be described with reference to FIGS. 19A to 19C. The pixel 10 includes a light-emitting element 13, a capacitor 16, and TFTs 11 and 12 (see FIG. 19A). When the light-emitting element 13 has a forward laminated structure (when the pixel electrode is an anode and the counter electrode is a cathode), and a forward bias is applied to the light-emitting element 13 according to the current direction of the light-emitting element 13, the first power source 17 is equivalent to The high-potential power source, and the second power source 18 is equivalent to the low-potential power source. On the other hand, when a reverse bias voltage is applied to the light emitting element 13, the first power source 17 is a low-potential power source, and the second power source 18 is a high-potential power source. The capacitor 16 stores the g...
Embodiment approach 3
[0103] Will now refer to Figure 5 to 7 The structure of the source driver 43 included in the display device of the present invention will be described. The source driver 43 includes a pulse output circuit 44, a NAND 71, a first latch 47, a second latch 48, and a selection circuit 46 (in the figure, the first latch 47, the second latch 48 and the selection circuit 46 Collectively referred to as SLAT) (see Figure 5 ). The pulse output circuit 44 has a structure in which a plurality of unit circuits (SSR) 70 are connected in cascade. The clock signal (SCK), the clock response signal (SCKB), and the start pulse (SSP) are supplied to the pulse output circuit 44. The data signals (DataR, DataG, and DataB) are supplied to the first latch 47. The second latch 48 is supplied with the latch pulse (SLAT) and the inverted pulse (SLATB) of the latch pulse. The write / erase signal (SWE or write / erase signal, hereinafter also referred to as WE signal) and the inverted signal (SWEB) of the WE si...
