A system may have windows. The window may have first and second window layers and a layer of material such as guest-host liquid crystal material between the first and second window layers. Electrodes on the window layers may be used to apply electric fields to the guest-host liquid crystal material to adjust the light transmission properties of the window. To ensure that a desired gap between the first and second window layers is maintained, spacers may be formed between the first and second window layers. The spacers may include key-and-lock spacers that have interlocking portions located, respectively, on the first and second window layers. Spacers such as photoresist posts can be attached using adhesive. Hybrid arrangements may also be used in which key-and-lock spacer structures are attached using adhesive bonds.
