Abstract: This disclosure provides an electronic device and a manufacturing method thereof. The electronic device includes a first substrate, a second substrate, a first supporting member and a plurality of second supporting members. The first supporting member and the second supporting members are disposed between the first substrate and the second substrate. The first supporting member includes a first bottom surface and a first top surface. The second supporting member is disposed adjacent to the first supporting member and includes a second bottom surface and a second top surface. The difference between the radius of the first bottom surface and the radius of the first top surface is defined as a first radius bias. The difference between the radius of the second bottom surface and the radius of the second top surface is defined as a second radius bias. The first radius bias is greater than the second radius bias.
