Abstract:
A diaphragm (10), a display panel (100), a display device (1000) and a household appliance. The diaphragm (10) comprises a substrate layer (11), a pattern layer (13) and a circuit layer (12). The pattern layer (13) and the circuit layer (12) are both printed on the substrate layer (11), since the circuit layer (12) and the pattern layer (13) are integrally printed on the substrate layer (11), a gap between the circuit layer (12) and the pattern layer (13) is eliminated, requirements for the clarity of pattern and character display after lighting are satisfied, the problems of the diaphragm (10) being prone to touch insensitivity and failure due to moisture are improved, and the positions of electronic elements on the circuit layer (12) match corresponding patterns on the pattern layer (13), such that the accuracy of matching positions is improved.
