First rib layers made of an inorganic material are formed in first frame regions of a first glass substrate. First resin layers are formed in first product regions after the first rib layers are formed. First functional layers which include light emitting element layers as a result of luminance of each of unit pixels forming an image being controlled and sealing layers covering the light emitting element layers are formed on the first rib layers and the first resin layers. The first rib layers and the first functional layers are cut along lines passing through the first frame regions while avoiding the first product regions in order to separate the first product regions from each other. In the step of cutting the first rib layers and the first functional layers, the first rib layers and the sealing layers are cut.

A first external tool (A) serially connected to an electronic controller (A) through a pair of communication lines (LANH, LANN) applies a high voltage (Vaa) higher than a normal control voltage (Vcc) to the communication line (LANH) when a program is written. The electronic controller (A) recognizes connection of the first external tool (A) by a comparison circuit (A) for monitoring a received voltage and a write-mode determination circuit (A), initializes a microprocessor (), and receives and stores an total control program (TCPRG) in a program memory (A) based on a content of a boot program memory (). During an operation of the electronic controller (A), the external tool (A) is removed and the high voltage (Vaa) is not applied to the communication line (LANH). Therefore, the electronic control apparatus is not erroneously placed in the write mode.
