Abstract
The present invention relates to a display device, using semiconductor light-emitting diodes, comprising: a wiring board which comprises a row line for providing a row signal, a column line for providing a column signal, a VCC line connected to a VCC input terminal, and a VDD line connected to a VDD input terminal; and an interposer which is provided on the wiring board, has pixels, comprising semiconductor light-emitting diodes, along a plurality of rows and columns, and comprises IC chips for controlling the pixel light emission. The interposer comprises: a first terminal connected to the row line and for transmitting the row signal to the IC chips; a second terminal connected to the column line and for transmitting the column signal to the IC chips; a third terminal connected to the VCC line and connecting the VCC input terminal and the IC chips; and a fourth terminal connected to the VDD line and connecting the VDD input terminal and the IC chips.
