Claim Text:
1. A method for manufacturing an electronic device comprising: depositing thin film transistors on a first glass substrate; joining the first glass substrate to a second glass substrate to form a glass substrate assembly, there being a gap between the first and second glass substrates; contacting the glass substrate assembly with an aqueous acidic solution for a time from 10 seconds to less than or equal to 10 minutes, whereby glass from each of the first and second substrates is removed to a depth only from 2.5 μm to less than or equal to 20 μm when the time has elapsed; rinsing the aqueous acidic solution from the glass substrate assembly when the time has elapsed; injecting a liquid crystal material into the gap; and wherein the contacting is performed after the step of joining but before the step of injecting.
