Filed: 1987-05-25
Abstract: PURPOSE:To improve the certainty of a switching operation by forming a gate wiring pattern between a photoelectric conversion element array and a TFT array to prevent an irradiated light from leaking to the TFT. CONSTITUTION:Only TFTs 3 are driven in one block by a driving IC 4, and the TFTs 3 in the block are all turned ON. Simultaneously, switches in a scan driving circuit 5 connected to the TFTs 3 in the block are sequentially turned ON. Thus, only the output of one photoelectric conversion element 2 in which the TFTs 3 and the driving circuit 5 are both turned ON is produced. Thus, such an operation is conducted in all the blocks to sequentially produce the outputs of all the conversion elements 2 at a slight time difference. A gate wiring pattern 6 is formed between the photoelectric conversion element array 2a and the TFT array 3a. Thus, the conversion elements 2 and the TFTs 3 are isolated to be disposed to effectively prevent a light beam C irradiated to the conversion elements 2 from leaking to the TFTs 3. Accordingly, the operations of the TFTs 3 are effectively performed.
