Abstract: A plurality of panels (40) are cut from a large substrate (mother substrate) including a lower large substrate (41A) and an upper large substrate (42A). For each panel (40), a frame-shaped seal (47) and a connection electrode forming section (C) are formed in the large substrate.

Since the upper side (47a) of the frame of a panel (40) is separated from the lower side (47d) of the frame of the upper adjacent panel (40) by an extension (C?) for the connection electrodes, these seal members are formed from a sealing material containing a higher density of spacers.

Abstract: A spread spectrum signal demodulating method whereby spread-code synchronous acquisition and carrier synchronous acquisition are performed using FFT at high speed, wherein a received signal, of which the carrier wave is modulated with a signal obtained by spectrum-spreading data with a spread code, is subjected to the FFT and the result of the FFT is stored in a first memory. The FFT result of the received signal stored in the first memory and the result of FFT of the spread code stored in a second memory are read out and multiplied to detect the correlation between the received signal and the spread code. A readout address of either the FFT result of the received signal or the FFT result of the spread code is shifted by an amount corresponding to a carrier frequency of the received signal.
