ABSTRACT:
Display equipment with exposed electrodes formed for establishing an electric connection with each of liquid crystal display, an electroluminescent light and a printed board. Anisotropic, electrically conductive elastomer pieces are placed between the respective exposed electrodes of the printed board, the liquid crystal display section and the electroluminescent light. A pressing rubber piece is placed on the side of the electroluminescent light which is opposite to its electrode side, and the component parts are received in and held by a holding frame which houses them from above the liquid crystal display section. Bent tip portions are inserted into the printed board and bent to fix the printed board and the holding frame. The electrode section of the electroluminescent light is pressed by the window head jump of the holding frame via the pressing rubber piece and is connected electrically in a stable manner. Even in cases where the liquid crystal display equipment has an electric connection section with a multilayer structure, the productivity may be increased since no solder is used. Arrangement of an anisotropic, electrically conductive member across the cut created by the removal allows establishment of an electric connection between non-adjacent electric circuit boards. If necessary, a plurality of such anisotropic, electrically conductive members may be arranged by mounting them on an insulating board which is then inserted between the electric circuit boards to be electrically connected.
